WebMar 18, 2024 · FST Values. The fixation index can range from 0 to 1, where 0 means complete sharing of genetic material and 1 means no sharing. For values equal to 1(meaning no sharing), scientists say that the populations are fixed. ... An Fst value greater than 0.15 can be considered as significant in differentiating populations (Frankham et al., … WebThe PhiPT (analogue of FST fixation index) value for genetic variability obtained over the four regions was 0.169 with high significance (P = 0.01). AMOVA analysis showed higher variance components within regions (80%) than among regions (20%). The two dendrograms obtained by Random Amplification of Polymorphic DNA (RAPD) data; and ...

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.
