Genetic and environmental effects on secondary sex traits in guppies (Poecilia reticulata).

Journal of evolutionary biology - 1 Jan 2005

Abstract excerpt

Male guppies (Poecilia reticulata) exhibit extreme phenotypic and genetic variability for several traits that are important to male fitness, and several lines of evidence suggest that resource level affects phenotypic expression of these traits in nature. We tested the hypothesis that genetic variation for male secondary sex traits could be maintained by genotype-specific effects of variable resource levels...
