Abstract:Incomplete speciation can be leveraged to associate phenotypes with genotypes, thus providing insights into the traits relevant to the reproductive isolation of diverging taxa. We investigate the genetic underpinnings of the phenotypic differences betweenSporophila plumbeaandS. beltoni.S. beltonihas only recently been described based, most notably, on differences in bill coloration (yellow vs. black inS. plumbea). Both species are indistinguishable through mtDNA or reduced-representation genomic data, and even… Show more
