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?

Accepted Answer

Hello everyone and welcome to today's video. So in today's video we have to identify the incorrect statement regarding sexual selection. Remember that sexual selection is a type of natural selection in which mates are selected based on certain traits. Now that we know this, let's jump over into our answer choices so that we can solve the problem beginning by answer choices A. And B. Because they're very similar. So answer choice A. We have that inter sexual selection refers to the selection between sexes usually when females shoes the males and then we have interest sexual selection, which is the selection within a sex. Usually when males compete with one another for mating rights. Since we're talking about inter sexual, it makes sense that it's going to be between sexes. And since we're talking about intra sexual, it makes sense that is going to be within a sex. These two answer choices are going to be correct and we're going to cancel them out because we're looking for the incorrect statement. Moving on, we have answer choice C sexual dim or fizz um can result from sexual selection. Remember that in sexual selection are selected based on certain traits. So let's set an example for example, we have deer. Now, male deers have antlers and females do not remember that sexual dim or fascism is differences that arise between the success. So this is an example of sexual dim or fizz. Um because the males have a trade and the females do not. So now why do the males have antlers than it is to compete with other males for the females. So it is an example of intra sexual selection or sexual selection. So it is actually a correct statement and we're going to cancel it out. Finally, we have answer choice. The sexual diamorphine traits are ineffective. This is very important at attracting mates or fighting off rivals for mates. Let's look back at these. Anders. Example, the reason why males have Anders is to fight off their rivals for mates. So it is very effective at accomplishing that. So it is a true statement. But then the reason why, for example, peacocks or male peacocks have their very color for feathers is to attract mates. So dear use there and there's very effectively to fight off rivals to find mates. And peacocks use their feathers or the color for feathers to attract mates so they're very effective. However, the answer choice says that they're ineffective, so it is an incorrect answer choice. We're going to highlight it as the final answer to our question.
