Admixture- Ethnicity Estimate - Ancestry Composition - Ethnic Makeup
Ancestry Composition tells you what percent of your DNA comes from different populations worldwide. The analysis includes DNA you received from all of your ancestors, on both sides of your family. The results reflect where your ancestors lived 500 years ago, before the advent of intercontinental travel.
For more scientific details about how these estimates work please visit the ISOGG site.
Below is a list of admixture analysis tests performed on family members, click the links to learn more about the tests:
23andme Ancestry Composition- My father, myself, my sister, my grandfather, my grandmother
Genographic 2.0 Deep Ancestry Test- My father
Family Tree DNA's Family Finder- Myself
Dr. McDonald's Biogeographical Analysis- My father, myself, my grandparents
Gedmatch Analyses- My father, myself, my grandparents
I want to post results for each person tested for all of these tests, but it will take up so much space, it's best reserved for individual blog posts. Please search for the label admixture if you are interested in seeing them.
What would you expect the admixture of a Palestinian Christian to be?If you would have asked me that question several years ago, I think I would have said Arab with a little European sprinkled in. The light eyes and hair of some Palestinian family members hint to contact with Europeans in the past. But, depending on what you read and what your natural assumptions are, you may think that Palestinians are ethnic Arabs for the most part or you may think they are native Levantines that descend from the ancient Jews.
Well, I was pretty close about the Northern European- it hovers around 5%. What I did not expect to see was a significant Italian/Greek element (which I believe is mostly from ancient times). Another surprise was that Arabian is only about 10-15%, actually a little less than the Roman element! The main core of our ancestry is deeply rooted in the Caucasus and Northern Levant. Typical population references include Samaritans, Middle Eastern Jews, Cypriots, Druze, and Lebanese (in order of closeness). Palestinian makes the list, but is usually not in the top 5. Maybe the reference group tested for Palestinian includes people from different areas and backgrounds. Dr. McDonald could tell that it was Holy Land DNA, which was a nice confirmation. Another researcher shared these comments with me and I do agree: Palestinian Christians are mostly descendant of Arabized/Christianized Samaritan Jews(indigenous Levantine); also slightly mixed with Ghassanid(Arabian), Crusader(North and West Euro), and Byzantine/Roman(South Euro).
Here are National Geographic's Geno 2.0 results for Regional Ancestry. Please note this is still VERY ancient admixture and unlike the results from the other companies, which show about 500 years up to 1000 years in the past. I found it very interesting that my father's first reference group is Georgian. This again shows a strong connection to the native people of the northern Levant. Georgians are some of the least admixed individuals today.
I will share specific test results from other companies in posts to come, so keep checking for the label Admixture if you are interested in seeing more.
This aspect of genetic DNA testing continually becomes more refined and more accurate, and I look forward to the coming advances the next few years will bring.
