- Which of the following statements about inter- and intra-sexual selection is FALSE? O Males are typically the sex experiencing intrasexual selection because they are generally limited by access to mates, whereas females are generally limited by access to resources. Intersexual selection can explain the occurrence of extravagant display traits in males such as the ornate coloration in guppies. Males competing against each other to aquire the best nuptual gift is an example of intrasexual selection. O Either intersexual or intrasexual selection may occur within a population, but not both.in sexual selection I need an explanation of why one sex is more choosy than the otherIntrasexual selection involves competition among one sex (typically males) for mating access to the other sex. Intersexual selection involves mate choice in which individuals from one sex (typically females) choose their mates from among individuals of the other sex. Imagine a group of males that is engaged in agonistic behavior, from which Male A emerges triumphant. Now imagine a female that is assessing all of the males that were involved in the fights, and chooses Male A. Explain why this situation shows how intrasexual and intersexual selection pressures are likely both at play in the trait selection.
