Marker polymorphism, heterozygosity and selfing in the Gambian population (n = 89^*).

*see materials and methods. †Abbreviations: Na = number of alleles, Ho = observed heterozygosity, He = expected heterozygosity, FIS = inbreeding coefficient, s = predicted selfing rate, p = frequency of predicted null alleles, Ne = number of predicted homozygous nulls, No = number of observed homozygous nulls.
