WebFSTAT is a computer package for PCs which estimates and tests gene diversities and differentiation statistics from codominant genetic markers. It computes both Nei and Weir & Cockerham families of estimators of gene diversities and F-statistics, and tests them using randomisation methods. The current version is 2.9.4. WebWhat is the heterozygote deficit Fst (inbreeding coefficient) for these two populations, in percent?

WebFor each group, the mean genetic diversity (h) with its standard deviation was computed for the eight loci, and the population structure among these groups was determined using the FST value (an index of genetic differentiation that ranges from 0 = no differentiation to 1 = all samples are fixed for a different allele). WebFeb 1, 2012 · Pairwise FST estimates showed slight genetic structure among clusters and a high FST between two clusters about 46 kilometers apart. Private alleles were detected in six of the seven clusters (i.e., alleles unique to a particular cluster and not found in any others). ...

WebThe fixation index (FST) is 0.03. The calculation involved obtaining allele frequencies and heterozygosity for both the total population and subpopulations. The FST was calculated using the formula FST = (H - Hs) / H, where H is the heterozygosity of the total population and Hs is the weighted average of heterozygosity of the subpopulations.
