Step by step
Solved in 5 steps
- Explain how sexual selection might lead to a)sexual dimorphism and b) members of one sex (usually male) having traits that do not enhance their survivalDefine sexual selection and describe an example of intersexual and intrasexual sexual selection in animals. Be sure to detail what trait(s) is/are being sexually selected.Use examples to explain sexual selection and its outcomes.
- Intrasexual selection favors traits that enhance direct competition among individuals of the same sex. are attractive to the opposite sex. increase survival. are easily adapted to change.Define selection and relate this to relative reproductive success?Explain the significance of reproductive isolating mechanisms and distinguish among the various prezygotic and postzygotic barriers.
- 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.Distinguish between intrasexual and intersexual selection.Define sexual selection?
