Question

Quizplus · Accepted Answer

Females of most nonhuman primate species do not always mate with the male who wins competitions. This is because they often have multiple partners and may mate with different males throughout their reproductive cycle. This helps to increase genetic diversity and may also help to reduce harassment from dominant males.

Answer: D
 Females carrying fetuses or young infants generally experience lower mortality rates in nonhuman primates. This is because they receive preferential treatment from group members, who may help to protect and provide food for them. This is especially true for highly social species where individuals form close bonds and engage in cooperative behaviors.

A and B are not true for most nonhuman primates. Females typically invest more time and energy in reproduction than males, and male-male competition is more common than female-female competition in primate societies.
