Concept explainers
a.
To explain: The cost and benefits to dominant individuals in a dominant hierarchy.
Introduction: Dominant hierarchy represented by the ranking of social status in which one animal has a higher status as compared to other animals which are lower in rank. In a certain group of species, the male is a dominant member while in certain other species females help in establishing dominant hierarchies. Establishing dominant hierarchy comes with certain costs and benefits.
(b)
To explain: The cost and benefits to subordinate individiuals in a dominant hierarchy.

- What are indirect fitness benefits of siblicide? When would an individual gain more from siblicide than from inclusive fitness benefits? When might it be worth it for a subordinate to fight to the death with its dominant sibling?arrow_forwardWhich of the following statements is NOT the reason why females are choosy? By being choosy, she can acquire advantageous genotypes for her offspring from her mates. By being choosy, she can acquire resource for her offspring from her mates. By being choosy, she can ensure that her male offspring can attract more females as well. Her seeming choosiness is a by-product of her stereotypical behaviors exploited by the males for mating gains. All listed above are reasons why she is choosyarrow_forwardEarlier explanations of altruistic behavior as a form of group selec-tion have been supplanted by Hamilton’s hypothesis of kin selection. What distinguishes kin selection and how does it accord with the no-tion of inclusive fitness, the relative number of an individual’s alleles that pass to the next generation?arrow_forward
- Why imprinting is considered as a learned behavior and not an innate behavior?arrow_forwardWhat relationships qualify as kin?arrow_forwardQ1:Communication occurs when A) the stimulus-response reaction is altered. B) information flows in both directions. C) information is shared. D) an action by one individual alters the behavior of another. Q2. Bateman's principle states that, A) heritability of male traits is higher than for female traits. females experience greater variation in reproductive success than males. male and female reproductive success must be equal. males experience greater variation in reproductive success than femalesarrow_forward
- In a species of birds, males court females by dancing and subordinate males are seen to join a dominant male and help in his dancing displays, though the subordinate receives no mating opportunities. If the subordinate male DOES NOT inherit the dominant male's territory upon its death, how would you explain this cooperative behavior? O Altruism, because the subordinate is receiving direct benefits O Mutualism, because the subordinate is receiving direct benefits O Altruism, because the subordinate is receiving indirect benefits O Mutualism, because the subordinate is receiving indirect benefitsarrow_forwardWhich 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.arrow_forwardWhy is long-term parental care not associated with having many offspring during a reproductive episode?arrow_forward
