There are several errors in the quoted text.

E.g.,

The X chromosome is a nuclear chromosome. Mitochondrial DNA is from the mitochondria, and is not from the X chromosome.

Also, the girls pictured story is well known. Their parents have not-too distant admixture of Africans and Europeans. It is not accurate to label their mother “white” and their father as “black”. Both had mixed ancestry. The long shot regarding the alleles for pigmentation is because there are several points in the DNA which is responsible, and the light colored daughter got the low probability case where she inherited from her darker father his minor alleles for low pigmentation.

First off, “Q” is in reference to the Y haplogroup in the human Y clade. Haplogroup Q is rare in Iceland and Norway. More importantly, these higher level haplogroups for the Y are very old, and can be from very long paths of descent over hundreds and thousands of years from a one-off event a long time ago.

Certainly there are problems with contemporary racists trying to exploit genetics for their own nefarious ends.

And, old-fashioned racists can be shown to be quite far from what is known about H. sapiens as illustrated by genetics.

There is a whole lot to be written on this, and a couple of years back I had started an outline to touch on the crossroads of genetics and racism. It’s a big topic, and several of the more prominent bloggers on this topic have dodgy backgrounds, something nearly everyone seems to want to overlook.

Time for you to start a series on genetics like Obdi is doing with stats perhaps?

I’d like to see it.
