Allelic richness (mean number of alleles per polymorphic locus) of the CAM markers in relation to genetic distance from zebra finch.* A: All 24 CAM markers included; B: Six CAM markers with 100% primer sequence similarity to chicken (and zebra finch); C: Six CAM markers with poor primer sequence similarity to chicken (but 100% identical to zebra finch). Genetic distance, genetic distance of the genotyped species from zebra finch (Taeniopygia guttata) DNA:DNA ΔTm hybridisation distance [33]. *Four individuals were genotyped at 24 loci for each of 11 species (including zebra finch Taeniopygia guttata but excluding chicken Gallus gallus; see text).
