Chapter 51.4, Problem 1CC
Summary Introduction
To determine: The justification of the concept of the indirect selection of the genes in an individual, due to the help and aid to the offspring of its sibling.
Concept introduction: The survival of the species depends upon the principles of the “altruistic behavior” and the “inclusive fitness” in the species. The altruistic behavior includes the volunteering of species of animals in assisting other individuals of the same race to raise progeny by mating. These species provide food to the other individuals in the species leading to their survival and mating. It is studied under the kin selection theory.

Assume 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.
In some cases, males or females do care for young of their own species that are not their own, as when certain male fish take over and protect egg masses being brooded by other males or when female ducks acquire ducklings that have just left someone else’s nest. Propose alternative hypotheses to explain this phenomenon. Under what circumstances might adoptions actually raise the caregiver’s reproductive success? Under what other circumstances might adopters help nongenetic offspring as a cost of achieving some other goal?

 why do females have a greater disadvantage compared to males concerning sexual reproduction? How has this difference between the sex shape sexual selection in general? Choose one form of communication and explain how it is used by competing sex is attracting a mate.

- Ecology regarding sexual selection: In zebra finch females prefer males who have a larger yellow cheek patch. Researchers investigating this preference think that females must benefit from choosing males with large cheek patches. Provide three hypotheses regarding the direct, or indirect benefits, she might receive.arrow_forwardIn the eclectus parrot (Eclectus roratus), mothers sometimes take parental favoritism to extreme lengths by killing their sons, but never their daughters (Heinsohn et al. 2011). Sex-specific infanticide occurs more often at nests that can be flooded during the rainy season. Sons spend longer in the nest than daughters. Link this factor to why it might be adaptive for a parent parrot to kill a son in a vulnerable nest occupied by offspring of both sexes.

- Nursing bees take care of the queen and newly hatched bees. However, nursing bees themselves do not reproduce. How could natural selection act upon such behavior? Because this behavior does not directly benefit the nursing bee itself, it is not favored by natural selection. Because this behavior increases the number of surviving offspring that share genes with the nursing bee, it is favored by natural selection. Because this behavior selectively decreases the number of offspring harboring non-similar genes with the nursing bee, it is favored by natural selection. Because this behavior does not increase the number of surviving offspring that are identical in genes with the nursing bee, it is not favored by natural selection.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_forwardPhalaropes are shore birds with brightly colored females and dull colored males. Females are larger than males and compete with each other for access to males. Considering sexual selection theory, select the idea(s) below that seem(s) most plausible in light of the pattern of sexual dimorphism? Pick all that apply This is a picture of a brightly colored female: O Females incubate eggs and care for the young. Males incubate eggs and care for the young Males are choosy. males are not choosyarrow_forward
- You are raising a stock of Drosophila flies in which you have clipped off the wings of each individual. Assume that this treatment does not disrupt their mating success (it would). If you clip off the wings in each subsequent generation, what would you expect to observe in the 50th generation? Why? This is an example of whose ideas in evolution?arrow_forwardIn the context of the runaway sexual selection hypothesis, what role does female mate choice play in the evolution of exaggerated traits in males? Females ignore males with exaggerated traits in favor of other factors such as resources Females display exaggerated traits themselves to attract males with similar traits Females have no preference for males with exaggerated traits Females actively select mates with these traits, leading to their exaggerated developmentarrow_forwardSuppose there is a type of deleterious mutation in a particular human gene that causes death very late in life. Such mutations happen in about one in every million births, and can be passed on to descendants. Which statement about this allele is false? At equilibrium, the frequency of this allele will be zero. Selection against this mutation is weak compared to an allele that causes death at an earlier age. Medical advances that extend human lifespan will increase selection against this allele. Selection against this allele depends on the rate of extrinsic mortality.arrow_forward
- Give typing answer with explanation and conclusionarrow_forwardSuppose a person does a study on tail length in skinks (a type of lizard). She measures the tail length of 10 Southeastern Five-lined Skinks and 10 Broad-headed Skinks. (Look these up on Google if you want to see what they look like!) The average tail length of her Southeastern Five-lined Skinks is 12.7 cm, and the average tail length of her Broad-headed Skinks is 13.2 cm. What can she conclude at this point? Question 5 options: Broad-headed Skinks, on average, have longer tails than Southeastern Five-lined Skinks Southeastern Five-lined Skinks, on average, have longer tails than Broad-headed Skinks She doesn't have an answer yet because she hasn't analyzed the tail length data The two skink species most likely have the same average tail lengtharrow_forwardIn a particular bird species who live socially, we sometimes see an individual in the social group helping to rear the offspring of its siblings, rather than finding a mate and reproducing itself. Describe the expected relative importance of direct and indirect fitness benefits to the individual helper, explain your answer. Explain how this same helper could improve its fitness by helping raise the offspring of an unrelated couple.arrow_forward
