WebJan 4, 2024 · In population genetics a common analysis when considering the genetic structure of a population is to examine isolation by distance - the relationship between the genetic difference and the geographic distance between populations. Commonly Fst (the P of variation attributable to differences between rather than within populations) is used as … 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. If See more This comparison of genetic variability within and between populations is frequently used in applied population genetics. The values range from 0 to 1.
