23andme - Genetic Testing Explained for Ethnicity

There are many genetic testing facilities out there today. This post is going to focus on 23andme and why I chose this for my genetic testing.

Chromosomes


We all have 23 pairs of chromosomes, however, we are all unique. Unless we are identical twins but even that has caveats that I won't go into here. We get 50% of these chromosomes from our mother and 50% from our father, but we do not get equal amounts of DNA from our grandparents and the farther out in your family tree you go the more diversified these amounts get.  We do not get the same grouping of DNA as our siblings even though we get 50% of the material from each parent in the form of chromosomes, it not exactly the same allocation of mirrored DNA.

We can go out about 7 generations for what is known as autosomal DNA. Autosomal DNA is reduced in effect each generation farther back you go.

Your autosomal DNA is most useful to help you locate relatives who might have information of a part of your family tree that you need help in unravelling. This is very helpful in finding your past if you are adopted, or if you are not sure about your paternal link. Or simply if you have questions regarding a brick wall you have found in your tree. Closer relatives have more clues, but even a distant cousin may have information that will help you.

Basically what generation you find yourself related to a person one back on your grandparents is your connection. So if you are 2nd cousins you are related by great grandparents. If you are 5th cousins you are related by 4th great grandparents. If you get a reading that says 5th to distant cousins you can set a parameter that is 4th to 6th great grandparents. Still, the rule of thumb is with the fading that takes place each generation out, you can assume that you would not find a connection more than 7 generations out.

Counting you as the first generation, then your parents then your grandparents your autosomal DNA is going to help you locate genetic family relations out to about your 5th great-grandparent level, 6th great is the stretch. Still, that is a lot of information! Each generation doubles the number of people from the generation before. So you are one, your parents are two, grandparents are four. At the 5th great-grandparent level, you have 128 people you descend from!

Which brings us to what I call fading DNA. You get 50% of your DNA from each of your parents, but they got a unique set of DNA from each of theirs'. This is compounded the father out you go. This is apparent when siblings test. As you go farther out, the distribution is never equal, so yes you get 50% from each parent but you do not get an even 25% from each grandparent, the farther back you go the more skewed this is, and also the strength fades out each generation you go back, until you hit full fade and do not see it anymore in a genetic test.

My brother and I are only 82% genetically alike! This proves that we are full siblings or we would be less than 50% alike. However, it also shows that we received different combinations of genetic material from our own parents. The farther you go out through your family tree you will not have 100% of all of your ancestors DNA and each generation loses some from the one before.

This plays a role in what cousins you will match. The more distant the cousin the higher the probability that one will match one sibling and not both. This also plays a role in what ethnicities will show up for you vs a sibling. For example, I show Ashkenazi and my brother doesn't, and he shows Finnish and I do not at the same marking place dating back to ancestors who lived in the 1700s are at the 6th to beyond generation out. This is not a problem, actually, it is an asset. Having your siblings also test will result in more matches for cousins, also a potentially greater understanding of your ethnicity, and therefore more clues.

Ethnicity

The one thing that is true about ethnicity is it is not one thing for most of us. 

MtDNA and Y-chromosome DNA go out thousands of years and in a way can be described in a way as human evolution.

Both men and women have mtDNA which is given to them by their mothers. Every child only gets their own mother's mtDNA. Y chromosome DNA is given to only male children. Only males have a Y chromosome. This is shown in biology class as the X and the Y. In general women are XX and men are XY. There are exceptions such as XXY but for the mass majority of humans, this is how it works.

You will receive an ethnicity reading based on your X or mtDNA if you are a woman or a man, but you will not receive Y information if you are a woman, only if you are a man. The X and the Y are considered sex chromosomes, they go back thousands of years.

This has zero to do with your autosomal DNA

The mtDNA shows the line from mother to daughter only in a straight line to infinity because one is built on the one before to the EVE. This code is handed to a female from her mother and she hands it to her female and male children but a male doesn't pass this on. When he has children they will receive the mtDNA from their own mother. For females, mtDNA is a straight line handed down from every mother before them in their direct female line.

For a man, his Y chromosome is going to show him all of the fathers in a straight line before him. A man will have mtDNA from his own mother but will not pass this onto his children. The Y information will be passed onto his son. This is done every generation in an unbroken line so this information can show you the travel of your particular male line going back thousands of years.

So with your mtDNA reading and your Y chromosome reading you are looking at a history that follows your direct female line, that is handed down mother to daughter in a straight line, and also to the son but is not repeated through him.

Also through the Y, you are looking at a history that follows the direct male line and his handed down from father to son unbroken for thousands of years. These male haplogroups can show how populations of people travelled and left their mark in the distant past to the present day.

Autosomal DNA - Ethnicity 

Autosomal DNA readings for ethnicity is like a bowl of soup. 

What is the genetic soup in your autosomal DNA? Let us make an old fashioned soup. We are going to put into this soup meat, carrots, celery, onions, tomatoes and potatoes for a basic hardy soup. We are using a big pot to cook it up in. Now it is finished and I am dishing out the bowls. We are serving 6 people. Now, these 6 people are siblings and each gets a bowl of soup. It all came from the same pot, it all has the same ingredients but each bowl is unique.

Some bowls will have more meat, some will have more potatoes and carrots etc., all will have the juice of the tomatoes and flavour of all that went into the soup. It is the same soup, but as it is dished out each person will get a bit different portion of what went into the soup.

When you take a genetic test looking for ethnicities from 23andme or another test you will receive a breakdown of what ethnicities are in your DNA. Many people think this is taking them far back in time and do not understand it is only going back about 7 generations.

An example could be so much percentage of the following, Irish/British, French/German, Scandanavian, Askenazi, Native American, various groups of Asian, and Sub-Sharan African. These will be represented as percentages, but what is not clear is many groups of people have comprised of these mixes already.

For example, many British people have a lot of German in the mix already from centuries ago, and Scandinavian too. Italians have many different mixes already going very far back in time. Dutch doesn't come up as an ethnicity on its own, but they are also a nation that has many generations who have only ever lived in the Netherlands. Autosomal DNA presents the genetic ethnicity of about the last 7 generations so to about the 4th great grandparents.

Proving You are Native American

Americans looking to prove their Native American ancestry will often be disappointed. There is no genetic proof to be Indian of any tribe and to use a genetic test for that is not allowed. There are labs that claim they can do that and that has been said to be fraudulent.

There are card carrying members of tribes who have taken a genetic test and come out no Native American showing in their DNA. That upsets some people very much and they do not understand it.

To be a member of a tribe is a socio-political act. We are talking about nations and treaties and a paper trail leading back to an ancestor who was pronounced to be a member of a tribe in the not so distant past in the USA.

23andme looks for Amerindian DNA. Not surprisingly many people who are of Mexican decent (have ancestors from the nation of Mexico) or from South America, have strong Native American percentages showing up. The reason is there are a lot of indigenous people in these areas AKA Amerindian.

In the USA there are a lot of mixed race people who have a connection to a tribe. Their test is very disappointing to them when it comes back with a no Native American reading. Coming back with a negative reading doesn't remove someone from their tribe and coming back with a positive reading will not be enough to get someone added to a tribe.

Why are some card-carrying tribal members coming back with no Amerindian DNA? Some reasons might be of the following explanations for Cherokee people. There is the Moytoy line of the Cherokee, for example, through a man who came to North America from Kent England who was of French Norman decent.  He married a Shawnee woman and is the father of the Moytoy.

Cherokee also shows a strong connection to the Middle East. They wore turbans for example. Cherokee maybe a mixed race people and may have a connection to what is known as Melungeons.

The Navajo have been traced through the Y chromosome to match people in Siberia Russia who are reindeer herders, and the location is Central Asia, not East Asia.

We also have the stories and evidence of the Clovis people and Solutreans living in the Americas during the Ice age. This is hotly debated but would suggest if it is true some genetic material that was not Amerindian did exist on the continent in people who would be considered indigenous.

You may show positive for Native American on a DNA test but this will not allow you to join a tribe, and you maybe in a tribe and come up with no Native American and this doesn't take away your history.

Good reasons to take a DNA test are self-discovery, tracing your family history more in depth and finding living family that you didn't know you have.

In addition, 23andme also offers health testing. It is interesting and you can find out your true blood type, your traits, your genetic strengths and weaknesses and what medications would work for you and which you should avoid before you take them.

If you are interested in genetic testing to find your true ethnicity and maybe even a little bit about your health traits I encourage you to purchase a 23andme testing kit.

Looking back in 2016 and forward to 2017 !

Looking back to 2016: We did three exclusive more day tours in Tuscany


and numerous one and more day tours in Alsace and Burgundy.
We met so many interesting and sweet people again this year. Thank you all !


For the first time we shipped local wines in cooperation with IZIwine and Burgundy Online to mainly the USA but also to countries like Australia. More to come in 2017 with our WineClub.

Last but not least we did some great genealogy research (thanks to Terry Smits) and tours. Ancestry research brought us to Verdun, St Avold, numerous locations in Alsace and also to Germany.

American World War I & II Military Attractions in Alsace-Loraine, France

From TripAdvisor

My spouse and I have travelled throughout Europe over the past 15 years with other tour guide services and although they were all very satisfactory, our interest was to request a private and professional tour guide with genealogy expertise that would take us to my family's roots in the Alsace-Lorraine region of France. Also, a tour guide with knowledge and experience of visiting the many American Cemeteries, Memorials and other renowned battle sites within Alsace-Lorraine. As background, I am a retired U.S. Army Veteran who served over 32 years both Active duty in Vietnam and Reserve duty with the Cross of Lorraine Division-79th ARCOM, formerly 79th Army Division with distinguished service in both World War I & II.


My request was for a customized 4-Day Private Tour service that included transportation and much appreciated language skills. As a follow up, we contacted Pieter Smits and spouse Terry Smits Moren who were exceptional with coordinating in advance the details of our visit. This was the beginning of a friendly relationship that added to our enjoyment throughout the tour by providing knowledge in-advance of our family's roots in Alsace, as well as, locating World War I & II military points of interest that I was familiar with from other sources. What was most outstanding was their assistance and patience with unforeseen circumstances that arose with researching various genealogy details; as well as, tour of the largest WW I American - Meuse-Argonne Cemetery near Verdun and the largest WW II American - St. Avold, Lorraine Cemetery near Metz, France.


Another highlight of our trip included a visit to the charming town of Colmar with it’s fine restaurants and close by wineries that featured tastings like none other… Pieter was especially knowledgeable of the wines and his unique understanding of the region’s viticulture.

This was a life-time experience for us and in good faith, I recommend JSwinetours - Day Tours -- Pieter Smits services to others who have similar interests and needs of a professional tour-guide with first-hand knowledge and experience for touring the Alsace-Lorraine Region of France...

Charlemagne: Literally the Father of Europe

The geographic location of Alsace being on the boarder of France, Germany and Switzerland has put it in the center of much activity over the centuries.

In our last blog post we covered the Iron Age Celts, the Romans and now more about the Franks. Here we will begin with Charlemagne.

Charlemagne


To view the original painting by Albrecht Dürer you may wish to visit the Nuremberg National Museum.

Charles the Great, Charles the I, Charlemagne was born on the 2nd of April in the mid 700's (the exact year is cited differently depending on who you read), and he died 28 January 814. He was king of the Franks taking the throne in 768, king of Italy in 774, and the first Holy Roman Emperor in 800. If you would like to go back further in time you might want to look at Constantine who settled the Franks on the lower left bank of the Rhine. 

He founded the Carolingian Empire, which would be the beginnings of what is now France and Germany.



If you look carefully on this map you can find Strasbourg on the line of the green and yellow areas. It is interesting to read about the Carolingian Empire and see which countries were fully in this, and which were partially in this.  


Charlemagne left us his genes.

Charlemagne left more than policies in his empire, and yet another reason to be called "The Father of Europe", he left his genetics too. Too say he was a ladies man seems a bit of an understatement. Depending on who you read he had 20 or 18 children of record. These are listed out of 8 of his 10 wives or concubines, which may or may not reflect all of the children accountable to him. He is listed as one of the top 10 people with the most decedents. Estimation of half of the population of Europe (250 million people) 100 million in the U.S.A. and another 250 million across the world. 

His pedigree is clear. If one should choose they can trace his line all of the way back to Adam and Eve. Regardless if you find this an impossible myth or not, the possibility to trace him back that far exists. One must never loose site of why pedigree charts started. Ah, yet another subject but it is the "divine right of kings"which is the right to rule. Still to this day pedigree charts are the most valuable possession of royals.You will find the Adam Pedigree here and you will find Charlemagne in the line of France.






Charlemagne left the Alsace region to his son Louis the Pious. Charlemagne's home was in Aachen, Germany. Charlemagne enjoyed hunting in the Vosges

Back drop of your genealogy. 

If you are researching your family tree and you manage to make it back to the Medieval times chances are good on one line or another you will find you descend from Charlemagne. What is nice about this is if you are working on a large family tree this work will have already been done for you. If you find what is known as gateway ancestors you can depend on established pedigrees. Click here to view the decedents of Charlemagne.

Oh one last thing, Charlemagne is behind the Hapsburg (Habsburg) who have castles in Alsace and all over Europe, and the Plantagenet who are behind all U.S.A. presidents with the exception of Martian Van Buren. One castle in Alsace we visit regularly with JSwinetours is Haut Koenigsbourg who the first named inhabitants were the Habsburg family.
