Not all DNA companies are the same. Ancestrydna does not test yDNA
MtDNA (Mitochondrial) -- the paired 23rd chronosomes. It only tests the
paired 1-22 chromosomes, called autosomal.
I think the important thing to take from Carl's post and the news
reports is that five companies did the same test (which had to be
autosomal) and all gave different results for identical twins. While
it's "fun" to think you are 1/3 rd this and 1/3 that, it should all be
taken with a large grain of salt. As for linking potential cousins to
cousins, that is a different process, but the fact of finding different
racial makeups in identical twins is just embarrassing to say the least
for the five companies involved. No doubt they all think their results
are correct, but that can't be so.
So I'm with Vi on this one.
