But for those who argue that Fst is not used as, or thought of as a measure of population subdivision, I offer http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1206343/pdf/ge1391457.pdf and the 1,700 papers that cite it as evidence to the contrary. <br /><br />Please demonstrate where I am in error, TwoYakshttps://www.blogger.com/profile/18004999495564178762noreply@blogger.comtag:blogger.com,1999:blog-6222564902180069698.post-89009625016747585112010-10-10T15:27:51.537-08:002010-10-10T15:27:51.537-08:00Adam: Fst is calculated for a group of populations...Adam: Fst is calculated for a group of populations, not one. Hs is the averaged subpopulation expected heterozygosity, and Ht is the over-all expected heterozygosity. The idea is that Fst supposedly measures population sub-division. This is one of the ways that you can have deviations from HWE. It has long been used for exactly this purpose.<br /><br />You are correct in saying the two TwoYakshttps://www.blogger.com/profile/18004999495564178762noreply@blogger.comtag:blogger.com,1999:blog-6222564902180069698.post-36753249889414735402010-10-10T14:58:24.504-08:002010-10-10T14:58:24.504-08:00I don't see the objection you're raising h...I don't see the objection you're raising here. My understanding is that F_st is intended to show how far a population deviates from HW equilibrium. The case you are talking about covers two distinct populations that by hypothesis do not exchange genes, and so HW equilibrium doesn't apply here. Maybe I am not 100% clear on the example, but it looks like you're saying that the Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6222564902180069698.post-3755636022981051182010-10-09T12:33:50.610-08:002010-10-09T12:33:50.610-08:00Yeah, unforntunately this population genetics post...Yeah, unforntunately this population genetics post is heavy with the jargon.
