WebMar 2, 2011 · G’ST and Jost’s D behave quite well in some cases, e.g. high mutation rates and two populations (Fig. 1, left), closely tracking the “true” divergence as measured by coalescent FST. However, while GST is limited to low values when heterozygosity is high, G’ST or D are in many cases biased upwards, rarely falling much below one even ... WebApr 26, 2024 · 1 Introduction. Genomic analyses that calculate F ST values frequently aim to separate neutral contributions to F ST caused by population histories from locus-specific contributions due to non-neutral evolution. However, different populations have different histories and are influenced by different factors that affect mutations, genetic drift, and …

WebFst values ranged from 0.07 between the ML and KP groups separated by a narrow land connection, to 0.12 between the KP and PWS groups isolated by ocean water and icefields.
