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.
