Extreme polymorphism in a Y-linked sexually selected trait.

Heredity - 1 Mar 2004

Lindholm A K, Brooks R, Breden F

Abstract excerpt

Males of the livebearing fish, Poecilia parae, exhibit one of the most complex polymorphisms known to occur within populations, whereas females are monomorphic. We describe five distinct male colour morphs and an associated size dimorphism, and demonstrate through pedigree analysis that the locus or loci controlling the male colour polymorphism is linked to the Y-chromosome. Field surveys from 1999 to 2002 of...
