Low Genetic and Morphometric Intraspecific Divergence in Peripheral Copadichromis Populations (Perciformes: Cichlidae) in the Lake Malawi Basin

Table 1

Genetic diversity in two Copadichromis species, genotyped at six unlinked microsatellite loci. N: sample size; Na: mean number of alleles per locus (direct count); AR: allelic richness (i.e., standardized for minimal sample size 40 and 53); Ho: observed heterozygosity; He: unbiased expected heterozygosity. For each population, the P values for the single-locus tests for departure from Hardy-Weinberg equilibrium are tabulated. Populations: Chilumba (CH), Nkhata (NK), Nkhotakota (NO), Mbenji Island (MI), Senga Bay (SB), Chenga trawl (CT), Nkhudzi Bay (NKU), and Lake Malombe (LM).
