  • "Cryptic choice allows females to preferentially choose sperm. Females are thus able to mate multiple times and allocate sperm to their eggs according to paternal phenotype, or according to other characteristics. In some cases, such as in the yellow dung fly, certain male traits will affect the fitness of eggs laid in particular environmental conditions. Females can choose sperm based on male quality as a function of its interaction with the environment. In other species, such as the fly Dryomyza anilis, females preferentially choose sperm from one storage location over another. Males of this species have developed behaviors, such as abdominal tapping, to increase their number of sperm stored in the favored storage site." (Wikipedia)
