Genetic basis of sexual dimorphism in the threespine stickleback Gasterosteus aculeatus.

Heredity - 1 Feb 2011

Abstract excerpt

Sexual dimorphism (SD) in morphological, behavioural and physiological features is common, but the genetics of SD in the wild has seldom been studied in detail. We investigated the genetic basis of SD in morphological traits of threespine stickleback (Gasterosteus aculeatus) by conducting a large breeding experiment with fish from an ancestral marine population that acts as a source of morphological variation. We...
