Genic capture theory
WebJan 1, 2024 · Some researchers have suggested “genic capture” as an explanation (e.g., Rowe and Houle 1996); given that the male traits under female selection are condition dependent and that male condition is in turn encoded by a suite of genes (e.g., those controlling body size, metabolism, etc.), there is likely sufficient genetic variation present … WebJun 1, 2004 · The genic capture hypothesis offers a resolution to the question of how genetic variation in male sexually selected traits is maintained in the face of strong female preferences.

Genic capture is a hypothesis explaining the maintenance of genetic variance in traits under sexual selection. A classic problem in sexual selection is the fixation of alleles that are beneficial under strong selection, thereby eliminating the benefits of mate choice. Genic capture resolves this paradox by suggesting … See more The key quantity for genic capture is vaguely defined as "condition." The hypothesis only defines condition as a quantity that correlates tightly with overall fitness, such that directional selection will always increase … See more Genic capture can also play a role in accelerating adaptation to new environments. See more Genic capture was proposed as a simpler alternative to another theory explaining the lek paradox that proposed that sexual selection creates See more
