Sexual conflict resolved by invasion of a novel sex determiner in Lake Malawi cichlid fishes.

Science (New York, N.Y.) - 13 Nov 2009

Roberts Reade B, Ser Jennifer R, Kocher Thomas D

Abstract excerpt

Sex determination mechanisms differ among animal species, but it is not clear how these differences evolve. New sex determiners may arise in response to sexual conflicts, which occur when traits benefit one sex but hinder the other. We identified the genetic basis for the orange-blotch (OB) color pattern, a trait under sexually antagonistic selection in the cichlid fish of Lake Malawi, East Africa. The OB...
