Significance Predominantly diploid organisms shape the extent to which their haploid gametes and gametophytes experience selection. Although animals are thought only mild selection in stage, plants often strong When should parents limit exposure of when they strengthen this selection? We develop mathematical models that consider “selective arena” within male or (sperm pollen) compete for fertilization, examining how intensity selective arena evolves controlled by mother father. These predict substantial variation outcome, depending on whether mothers fathers exert more control over arena, with favoring stronger than fathers.
