Question
Suppose you were studying several species of monkeys. In one, males never helped females raise offspring. In another, males provided just as much parental care as females except for actually carrying the fetus during pregnancy. How does the fundamental asymmetry of sex compare in the two species? How would you expect sexual dimorphism to compare between the two species?
A) For the species in which the males never help raise offspring, the fundamental asymmetry of sex is small and sexual dimorphism should be lower than for species in which males always help raise offspring. B) For the species in which the males never help raise offspring, the fundamental asymmetry of sex is pronounced and sexual dimorphism should be lower than for species in which males always help raise offspring. C) For the species in which the males never help raise offspring, the fundamental asymmetry of sex is small and sexual dimorphism should be higher than for species in which males always help raise offspring. D) For the species in which the males never help raise offspring, the fundamental asymmetry of sex is pronounced and sexual dimorphism should be higher than for species in which males always help raise offspring.Explanation / Answer
answer - D.
For the species in which the males never help raise offspring, the fundamental asymmetry of sex is pronounced and sexual dimorphism should be higher than for species in which males always help raise offspring.
Explaination- The fundamental asymmetry of sex results from the fact that in most species, females invest more in their offspring to raise them properly than do males.This pattern has important consequences which are the female fitness is limited by the ability to gain resources needed to produce more eggs and healthier offspring and male fitness is limited by the number of females he can mate with in a time or in a specific geographical area. If males never helped females raise offspring then they should be fit and attractive so that female can choose them over other so sexual dimorphism will be higher. And if females prefer to mate with males that care for young or that provide the resources required to care the young ones,in this case sexual dimorphism reduced or less mattered so it is less in these males.
