sexual selection

n. Biology
The process in nature by which individuals with certain traits, especially secondary sex characteristics such as colorful plumage and large antlers, are chosen more often for mating and thus pass those traits on to their offspring.

sexual selection

the selection of mates on the basis of the attraction of or preference for certain traits, such as coloration or behavior patterns, so that eventually only those particular traits appear in succeeding generations. It explains the wide variety of sexual characteristics among the various species.
