Distributions of ancestry and heterozygosity in hybrid tiger salamander populations. Joint maximum likelihood estimates of ancestry and interclass heterozygosity show variation among populations within the California tiger salamander hybrid swarm (A-E). Here, S is the proportion of alleles derived from the introduced Barred Tiger Salamander. (F) Illustrates that the joint maximization converges on the closed-form MLE of the ancestry index for diagnostic markers.
