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 females
- Which of the following sexual traits is LEAST likely to have evolved due to male-male competition for mates, also known as intraspecific sexual selection?a) Enlarged femurs that an insect uses to kick other malesb) Brushes on the tip of a dragonfly penis used to remove sperm of other malesc) Mate-guarding behavior of a warbler during the female’s fertile periodd) Elongated tails of the male swordtail fish used during courtshipDescribe 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.Explain why sexual cannibalism represents an evolutionary paradox.
- Define 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.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.Compare and contrast reproductive strategies and forms ofsexual selection.
- 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?Two groups of participants read a description of a person called Mark, who was described as shy, introverted and good at mathematics. They were asked how likely each of the following statements were: a) That Mark is male; and b) That Mark is male and works as a software engineer. The group rated b) as more likely than a). In reality a) is more likely than b) because given his name, Mark has a very high probability of being a man. The combined probability of him being both a man and a software engineer must of course be lower. Why did the participants make this mistake, and what does this tell us about the way in which human beings make judgements about peopleMonozygotic twins: Question 2 options: a) Share 50% of their genetic material and if one twin has schizophrenia the risk of the other having the illness if 40-50% b) Share 100% of their genetic material and if one twin has schizophrenia, the risk of the other having schizophrenia is 10-15% c) Share 100% of their genetic material and if one twin has schizophrenia, the risk of the other having schizophrenia is 40-50% d) Share 50% of their genetic material and if one twin has schizophrenia the risk of the other having the illness is 10-15%
