The quantitative genetics of sexual dimorphism: assessing the importance of sex-linkage.

Heredity - 1 Nov 2006

Fairbairn D J, Roff D A

Abstract excerpt

Sexual dimorphism (SD) is a defining feature of gonochorous animals and dioecious plants, but the evolution of SD from an initially monomorphic genome presents a conundrum. Theory predicts that the evolution of SD will be facilitated if genes with sex-specific fitness effects occur on sex chromosomes. We review this theory and show that it generates three testable predictions. For organisms with an XX/XY...
