Male and female migration patterns, Jaume Bertranpetit.

Description:
Interviewee: Jaume Bertranpetit. Geneticist Jaume Bertranpetit speaks about the findings from Y-chromosome and mtDNA. studies. (DNAi Location: Applications > Human Origins > gene genealogy > Tracing ancestries > Male and female migration patterns)
Transcript:
Some years ago we did the first genetic study, in central Asia, studying mitochondria and Y chromosome. And for the first time in a given population, we could clearly establish what had, afterwards has been seen as a general rule, is that women move a lot and men stay in the place. So this general pattern that is something little astonishing, comes from DNA studies in the sense that, what we found in this first study in central Asia is that for Y chromosome one population is very different to the others. For mitochondria all of them are very similar. How to explain that? So the idea is very simple: mitochondria move, Y chromosome do not move. Or in other words, males stay in the place where they were born, women move from one place to the other, and in the sense what we find looking at mitochondria, looking at Y chromosome, it's different in the sense that these populations differ, but only in male lineages, and they do not differ in mitochondria. Say that in this way, mitochondria have been circulating, has been going around, and making homogeneous the populations. Maybe also establishing the links that population needed to survive.
