WebFixation index (Fst) calculation was implemented using Hudson method as in Bhatia (2013) and Hudson (1992). Fixation index (Fst) calculation was implemented using Hudson … The fixation index (FST) is a measure of population differentiation due to genetic structure. It is frequently estimated from genetic polymorphism data, such as single-nucleotide polymorphisms (SNP) or microsatellites. Developed as a special case of Wright's F-statistics, it is one of the most commonly used … See more Two of the most commonly used definitions for FST at a given locus are based on 1) the variance of allele frequencies between populations, and on 2) the probability of identity by descent.

WebFixation measures are commonly used not only to describe the nearness to fixation of a set of demes, but also to infer the values of the demographic parameters that cause the observed pattern.
