reproductive success

the degree to which an individual is successful in producing progeny that in turn are able to produce progeny of their own. Individuals vary in their success in finding mates and reproducing successfully. Natural selection is based on this differential reproductive success. The genetic and behavioral traits that lead to greatest reproductive success survive in a population over generations, whereas traits producing low reproductive success eventually become extinct.
