Asymmetrical expression of transsexual phenotypes in hummingbirds.

Proceedings. Biological sciences - 22 Mar 2001

Bleiweiss R

Abstract excerpt

I present evidence for asymmetry in the expression of transsexual traits in adult hummingbirds. Among females, individuals with male-like plumage are common and define a continuous range of variation. Among males, individuals with female-like plumage are rare and define discontinuous plumage morphs. Quantitative characters also distinguish transsexuals from other members of their sex, but the characters involved...
