Figure 3
Mean±1.96 SE number of alleles from 100 sets of 20 randomly drawn samples from the three populations. Results from pairwise Mann–Whitney U-tests between populations are denoted above the bars: ‘a’ is significantly smaller than ‘b’, which is significantly smaller than ‘c’ (significance at 0.05). Below each bar are the expected and observed percentages of heterozygotes at the corresponding population and locus.
