genetic structure of Pacific island populations

A new paper looking at the genetic structure of Pacific Islanders has just come out. The authors type nearly a thousand markers on 952 individuals from 41 Pacific populations. I've not had a chance to read the paper in any depth, but it looks really interesting. Studies of single loci such as the Y or mtDNA offer a very noisy view of human history as chance events in the history of the maternal or paternal line can distort the view of history that the Y or mtDNA give us. This kind of study (with many unlinked markers) offers a huge advantage over mtDNA or Y chromosome studies as it represents a truly genomic view of population history. This paper also nicely ties in with the recent paper on native american ancestry (using the same set of microsatellite markers) . Combined with the spate of papers on finer scale structure within continents (e.g. here and here ) this is a great time for learning about the genetic history of populations.

thank you for teaching about the history and diversity that has the articles and the genetic structure. this type of information helps me on my homework Buy Cialis left me at school

I think this is a very interesting topic to research about.
I'm sure that all that people who live in such islands have never tried viagra online , it is a very good way to make it work
