Re: Ancestry composition on the chromosome view

If you're asking a general question about chromosomes and how they're numbered, this is a good introduction:

If you're asking whether it matters that the small East Asian segment appears on chromosome #3 vs some other chromosome, there's no significance. It just happens to be the one chromosome still carrying some DNA that appears most similar to East Asian DNA.

However, the percentage is very small, and it could be just "noise" (an accidental combination of markers that resemble East Asian DNA).
