Distributions of FST for various marker types based on 10 000 simulated samples of 100 individuals from two populations with a true FST of 0.002. The sample parameters mean, median and variance ( × 10−6) are for microsatellites (eight loci): 0.0020, 0.0019, 1.4; allozymes: 0.0019, 0.0009, 19; mtDNA: 0.0020, 0.0014, 9.3; MHC: 0.0021, 0.0008, 25; Cpa112: 0.0020, 0.0014, 10.
