WebAug 14, 2024 · The variation value within the sub-populations (95% of total variation) was significantly higher than that between the sub-populations (5% of total variation). In addition, a high gene flow (Nm = 4.981) and a low fixation index value (Fst = 0.048) were obtained on the basis of Nei ’s genetic distance analysis. 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.
