- 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.Which 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 choosy 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. 
- The good genes model of sexual selection is a popular hypothesis for mate choice. What is an underlying flaw with the hypothesis that must be explained?The conscious selection of a mate is called: Question 5 options: Monogamy Polygamy Nonrandom Mating Random Mating Question 6 (1 point) How does sonar affect some species' ability to hunt? Question 6 options: Sonar incorporates neither light nor sound. Sonar relies on light, rather than sound. Sonar relies on sound, rather than light. Sonar incorporates both light and sound. Question 7 (1 point) Which of the following species undergoes random mating? Question 7 options: Lions Marine Sponges Humans Tigers Question 8 (1 point) Which of the following associative behavior specifically refers to a relationship in…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.
- You are observing a grouse population in which two feather phenotypes are present in males. One is relatively dark and blends into the shadows well, and the other is relatively bright and more obvious to predators. The females are uniform dark feathered. Observing the frequency of mating between females and the two types of males, you have recorded the following: Mating’s with dark feathered males: 13 mating’s with a bright feathers male: 32 Propose a hypothesis to explain why females apparently prefer bright feathered males. What selective advantage might there be in choosing a male with alleles that make it more susceptible to predation? What data would help test this hypothesis?What sorts of studies would we undertake in order to confirm that human mating behaviors are truly driven by biological forces, e.g., evolutionary fitness, rather than cultural or societal advantages?Johnston et al. estimate that 50% of males with the Ho Ho genotype develop scurs (instead of full horns). They also estimate that around 13% of the total male population, at birth, will develop scurs. The males who managed to get access to mating opportunities with females seem to show no preference for whether the females have horns or not. Thus in the adult mating population, mating is random with respect to the genotype at this locus. What is the frequency of the Hop allele in the population?
- What is purposeful control over mating by choice of parents for the next generation?You do not need the text from the image so font size does not matter. Please consider the figure, which contains data that were collected by Rice In the experiments that were performed by Ricei. males competed intensely for females, which resulted in selection for traits like 'high likelihood to remate with the same female' and 'high proportion among fertilised eggs fathered.'ii. only males experienced intense competition; females were obtained from a control population, in which no competition for mates was occurring, effectively fixing female responses.iii. males that were selected for success in mating competition were characterised by greater fitness.iv. when females were prevented from evolving compensatory life history traits, they incurred at least one cost for the benefits gained by males in increased reproductive success: greater female mortality (attributed to toxicity in male seminal fluid).v. once established, enhanced male traits were irreversible. Question 4…Think about how we organized the mechanisms of sexual selection (mate competition vs. mate choice; resource-based choice vs. non-resource-based choice, etc.). Based on this organization, choose the pair of examples from the list below that are most closely matched in terms of mechanisms of sexual selection. Male red deer engage in physical contests to determine who mates with a female. Male mouse lemurs engage in scramble competition for female mates. Peahen (female) chooses to mate with a peacock that has large eyespots in the tail feathers of his magnificent display. Question 8 Think about how we organized the mechanisms of sexual selection (mate competition vs. mate choice; resource-based choice vs. non-resource-based choice, etc.). Based on this organization, choose the pair of examples from the list below that are most closely matched in terms of mechanisms of sexual selection. Male roadrunner presents female with lizard 'snack' during courtship. Male butterfly transfers sodium to…
