Integrating information using DNA markers, Kenneth Kidd

Interviewee: Kenneth Kidd. Geneticist Kenneth Kidd explains his study of human DNA variation in nuclear chromosomes. (DNAi Location: Applications > Human Origins > Gene genealogy > Other genome regions > Integrating new information)

We're looking only at nuclear autosomal DNA. We're not looking at mitochondrial DNA, Y chromosome DNA, X chromosome DNA. There are a lot of researchers who have specialized in those areas. There are very few researchers who are looking at large amounts of nuclear autosomal DNA variation in large numbers of populations. And that's where historically we've been interested, and after all I'm a scientist in part to satisfy my own curiosity. There's no good method yet for integrating the information from all the different types of DNA. They're all telling a similar story on a large scale of African origins, a subset of variation coming out of Africa, expanding to different parts of Eurasia, and then a further subsetting, or derivative types going into the Americas. But they're telling it in somewhat different ways, and we haven't quite integrated all of that. But certainly on the large scale there's no major discrepancy.
