[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Remember when Julianna Marguiles was on a Find Your Roots episode on PBS?
They did the DNA test on her and the result was 99.9% Ashkenazi Jewish ancestry.  She excitedly said, "super Jew!"[/quote]

That's a pretty funny response, TBH.

- Ashkenazi Jew[/quote]
It was!  It's very nice that she's proud of her heritage.[/quote]

In case any of you wonders, there's no person alive whose DNA says he/ she is 99.9% African American or Hispanic.

So, yes, that 99.9% would be quite remarkable.[/quote]

Mine said the same thing (99.9 -- Ashkenazi Jewish). My husband had 1% or 2% Irish in addition to his 98% Ashkenazi.[/quote]

You all need to read up on these genetic testing companies - https://now.tufts.edu/articles/pulling-back-curtain-dna-ancestry-tests
Pulling Back the Curtain on DNA Ancestry Tests

some snippets:

[quote]Sheldon Krimsky: We don’t really know, because the companies selling these services—and there are close to 40 of them—don’t share their data, and their methods are not validated by an independent group of scientists and there are not agreed-upon standards of accuracy. People have sent their DNA to several of these companies and found differences in the results—though not necessarily radical differences. So you have to look at the percentages you receive back with skepticism.

Each company offering these services uses its own proprietary database of DNA samples called ancestry informative markers (AIMs) from current populations in Asia, Africa, Europe, and the Americas. From within those databases, they each select for a certain number of alleles—one member of a pair of genes located at a specific position on a specific chromosome—and in these spots, use the genetic variations known as single nucleotide polymorphisms (SNPs) as the basis for evaluating individuals. The markers—SNPs—are chosen because they have different frequencies across different geographical populations.

She has to understand that she’s not matching her DNA to someone from hundreds of years ago. It’s also quite possible for someone who is African American to get ancestry test results that say they’re 75 percent European. That’s because the chosen ancestry-information markers reflect only a small percentage of our DNA, and there’s actually more genetic diversity within the African population than between the African population and a European population. (For more about this, see dialogue one in a publication I co-wrote, “Using Dialogues to Explore Genetics, Ancestry, and Race” [PDF].)

And this - which is what I pointed out in an earlier post:

[quote]The importance of movement

If your ancestors and their offspring had stayed in one geographic region and never allowed outsiders to enter, it would be relatively easy to distinguish their DNA (and yours) from the DNA of people living in other regions. Over time, all of the inhabitants of your region would come to share specific genetic mutations (usually harmless changes in DNA), which would identify them as a distinct population, the same way a surname identifies members of a family.

But our ancestors didn’t stay in one place. For thousands of years, humans have moved about, leaving their genetic imprints wherever they procreate and making it increasingly difficult for geneticists to distinguish one region’s population from another’s.[/quote][/quote]

I'm sure there are flaws with the DNA testing.  I didn't need one to determine my ancestry.  Adoptees and others who have no other knowledge or proof of their ancestral background should be cautious, but that's not me.  It cannot be completely made up as Its relied upon in many ways.
