sexual selection

Show Summary Details

Quick Reference

The theory, proposed by Darwin, that in some species males compete for mates and that characteristics enhancing their success in mating would have value and be perpetuated irrespective of their overall value in the struggle for existence. Such characters would be used either in male display to attract females (intersexual selection) or in combat between rival males (intrasexual selection), and both could act at the same time.

Subjects: Genetics and Genomics.
