From: Detecting loci under selection in a hierarchically structured population
Example of FST distributions obtained under different migration models for single nucleotide polymorphism (SNP) data. The diversity of 1000 SNP loci (open circles) was simulated under a hierarchical island model with 10 groups of 100 demes for two combinations of migration rates within and between groups. The joint null distribution of FST and heterozygosity (30 000 grey dots) was then obtained under either a hierarchical island (a, b) or a finite island model (c, d) based on observed average F-statistics. \(\overline{F}\)ST is the weighed average F-statistics computed over 1000 loci.
