What is sexual selection? How is sexual selection similar to and different from other forms of natural selection?
Why might natural selection act more strongly on traits that improve reproductive success early in life rather than later in life?
So how can individual selection result in low reproductive rates or short life spans?

- How does competition influence natural selection? Is the presence of competitors a selective force?arrow_forwardAssume you are studying a species of slug where the eggs are fertilized and transferred to the male. As a result the male is not able to increase reproductive success by mating with multiple partners. Therefore which of the following about sexual selection in this species is not true? Females are more likely to develop traits that signal genetic quality to males. Females will be able to increase reproductive success with increased mating partners. Sexual selection in males will lead them to be choosy with what females they mate with. Sexual selection in males will lead them to mate indiscriminately when they find a female.arrow_forwardWhat are reproductive barriers? How do premating and postmating barriers differ?arrow_forward

- Describe thoroughly the selective advantages and disadvantages organisms that reproduce sexually have over those that reproduce asexually, as well as the ramifications of mate choice on the traits present in species. The following questions could help answer the question above. What are the advantages of sexual reproduction? What are the disadvantages? How do traits selected by sexual selection and those selected by differential survival mix in an animal species? i.e. is it more important to mate or survive? Use specific examples to illustrate your point. Your answers should indicate an understanding of the mechanism behind natural selection. Propose a scenario where asexual reproduction would be favorable.arrow_forwardIn social insects, colonies often consist of a queen and workers. The workers are typicallydaughters of the queen. The queen is the only reproductive individual—the workers aresterile. a) According to Hamiton’s rule, what is the maximum ratio of cost to benefit (C/B) for theworkers in order for this system to evolve?b) Some colonies of ants have multiple queens, which can be related to different degrees.Imagine that two sisters start a colony, so that they are the mother or aunt to allworkers. What is the maximum ratio of cost to benefit (C/B) for the workers to sacrificefor their aunts?arrow_forwardThe continued evolutionary exaggeration, across generations, of a sexual display trait (e.g., a trait used by males in attracting mates, like the peacock's tail) is most likely due to: a) stabilizing fecundity selection O b) directional sexual selection c) genetic drift d) heterozygote advantage e) directional viability selectionarrow_forward
