A The location of fox sparrow (Passerella spp.) specimens used in this example. B Linear regression between plumage score and genetic hybrid index for Passerella specimens from the contact zone. All allopatric individuals (18 P. iliaca, 5 P. unalaschcensis) were assigned to the parental populations to identify AIMs (δ = 1), and hybrid index was calculated in triangulaR. C Triangle plots built in triangulaR using all allopatric individuals assigned as parentals (uneven parental sampling) and D five allopatric individuals assigned as parentals (even parental sampling) to identify AIMs (δ = 1). Estimates of E hybrid index and F interclass heterozygosity from triangulaR were compared to those from bgchm, using AIMs (δ = 1) from both sampling schemes.
