1.In primate species that are not pair-bonded, we can predict that

Group of answer choices

females will provide more care for offspring than will males.

neither sex will care for offspring.

males will provide more care for offspring than will females.

both sexes will care for offspring equally.

2.Which of the following statements is true?

Group of answer choices

Patterns of courtship, mate choice, and parental care vary greatly within the primate order.

The same factors limit male and female reproductive success.

Studies of primate reproductive behavior cannot help us understand how evolutionary forces shaped the reproductive strategies of our hominin ancestors.

The reproductive strategies of living primates are not influenced by their phylogenetic heritage as mammals.

3.Which type of social group has the largest relative testis size?

Group of answer choices

pair bonded

one female, multimale

one-male, multifemale

multimale, multifemale

Solutions

Expert Solution

Ans 1-) Correct option is female will provide more care for offspring than will males.

In the primate groups , female give more parental care than males as males have to fulfill other responsibilities such as defending the territlry etc

Ans 2-)Correct option is pattern of courtship , mate choice and parental care vary greatly within the primate order.

Because of mate choice copying. It is due to social learning , which gives knowledge about potential mates after the observations of behaviour in mating as well as courtship of close conspecifics.

Ans 3-) Correct option is multimale ,multifemale

Either breeding in seson or non season , both the species have relatively larger size testis.
Arthopoids includes groups which are both multimales and multifemales. As compared to body weight,they have greater size of testis because seminiferous tubule which is present in greater volume produces spermatozoa in large number for the reason that sperm competition alwayz prefer male as they can produces maximum number of gamates .
