Sexually-selected differences in warbler plumage are related to a putative inversion on the Z chromosome

Large structural variants in the genome, such as inversions, may play an important role in producing population structure and local adaptation to the environment through suppression of recombination. However, relatively few studies have linked inversions to phenotypic traits that are sexually selected and may play a role in reproductive isolation.  Here we found that geographic differences in the sexually-selected plumage of a warbler, the common yellowthroat (Geothlypis trichas), are largely due to differences on the Z (sex) chromosome (males are ZZ), which contains at least one putative inversion spanning 40% (31/77 Mb) of its length. The inversions on the Z chromosome vary dramatically east and west of the Appalachian mountains, which provides evidence of cryptic population structure within the range of the most widespread eastern subspecies (G. t. trichas). In an eastern (New York) and western (Wisconsin) population of this subspecies, female prefer different male ornaments; larger ..., , , # Data from: Sexually-selected differences in warbler plumage are related to a putative inversion on the Z chromosome
