Final answer:
Monkeys with PPR and MPR show behavioral differences in their care for offspring. Shutting off the MPR may reduce male parental involvement.
Step-by-step explanation:
Monkeys with the PPR (postpartum reinvestment) and MPR (male parental recognition) exhibit differences in their behavior and responsibilities regarding offspring. Adult females have the ability to experience pregnancy and bear offspring, thus devoting more time and resources to care for young compared to males. On the other hand, juvenile females tend to pay more attention to primate babies within the group than do juvenile males. When the MPR is shut off, it is likely that the males' recognition and involvement in parenting tasks may be compromised. They may exhibit less interest or awareness of offspring, potentially resulting in decreased investment in their care and well-being.
