WebMar 29, 2024 · It is also important to consider colonial history when interpreting patterns of genetic variation in the Grassfields. For example, the Bamileke label was given to several smaller fondoms by the Germans during the colonial period ( 62 ), and this may explain their relatively high genetic diversity compared to nearby ethnic groups that have not had such … 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.
