Frequency of different DNA variations, Kenneth Kidd

Interviewee: Kenneth Kidd. Frequency of different DNA variation.

At every point where there's genetic polymorphism, each of the variant forms of DNA, for that segment of DNA which we can call a gene or not - in many cases it's not functional, but it's a segment of DNA - has variants. And it's the frequency of the different variant forms, the different alleles in different populations. So some forms may be very frequent in African populations and very rare in east Asians, for example.
