>Nope
yes
>those links
are probably accurate, i don't doubt it
it doesn't change what i said, at all
the DNA tests used for commercial use to sell to people to say what % of each ethnicity they are, virtually all of them are trash. that's a fact
now, what i said is also true:
>they [scientists] can do a DNA test and assign black, asian, white, and amerindian people randomly into 4 categories with a computer program and it is assigned to the correct racial category over 99% of the time, with just a few markers.
this is also true
one example:
>In this study of 1334 individuals, who self-identified as either African American, European American or Hispanic, we demonstrated that when the true underlying genetic structure and the self-defined racial/ethnic groups were roughly in agreement with each other, the self-defined race/ethnicity information was useful in the control of population structure...
ncbi.nlm.nih.gov/pubmed/16759181
it is a FACT that they can test whites, blacks, and asians and using just a few markers assign people into 3 categories corresponding to these 3 racial groups, with over 99% accuracy
it is also a FACT that most commercial "learn your ancestry" DNA tests tend to be bogus
another:
ncbi.nlm.nih.gov/pmc/articles/PMC1183530/
>In a recent study, when we looked at the correlation between genetic structure [based on microsatellite markers] versus self-description, we found 99.9% concordance between the two. We actually had a higher discordance rate between self-reported sex and markers on the X chromosome!
also:
>A complete leave-one-out validation experiment demonstrates that, using all available SNPs, assignment of individuals to their self-reported populations of origin is essentially perfect.

so these are what we know
- scientists can determine race with basically >99% accuracy using DNA tests
- most commercial DNA tests for the public are trash
