Summary Introduction
To determine: The difference between intrasexual selection and intersexual selection.
Introduction: Population density is the number of a specific type of individuals living in a specified area for a given period of time. The population density can be calculated for plants, microbes, humans, domestic animals, and others. The population density gives information about how many individuals are being supported by the

Clarify the difference between claiming that, a) some behaviours are genetically determined, versus b) some differences among individuals in behavioural phenotype are genetically determined. Are both claims valid in some circumstances? Use any suitable example you know about to justify your answer.
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.
Why would subordinate group (ex.women) accept a system of male dominance when such acceptance would seem to be against their interests? how does acceptance relate to the process and content of socialization?

- Does blood type determine your personality? In a study aimed at answering this question, a random sample of 100 adults was given a personality test, and a comparison was made between the scores on the introversion/extroversion scale and blood type (A, B, AB, О).

- What do arguments based on biological determinism assume?arrow_forwardOf which postzygotic barrier is the mule an example?arrow_forwardIntrasexual 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.arrow_forward
