A species of rotifer, a small freshwater invertebrate, lost the ability to reproduce sexually millions of years ago. A remarkable feature of its life cycle is the ability to withstand dry conditions. When the rotifer's environment dries out, so does the rotifer, and it can be blown to a new area. Rotifers that land in water will rehydrate and resume an active life. A major pathogen of these rotifers is a species of fungus that cannot survive drying. Some scientists hypothesize that drying rids the rotifers of this pathogen. (b) Why might the ability to withstand drying reduce any potential advantage of sexual reproduction in this rotifer species?

Hello everyone. And in today's video, we have to follow a problem. So in terms of habitat colonization, how to a sexual re producers differ from sexual re producers. So let's go over answer choices so that we can solve the problem. Keep in mind the things that we need for a sexual producers to reproduce and sexually producers to reproduce. So for answer choice B. We have a sexual producers can have a more a more diverse source or a sexual Re producers have only one individual contributing genes to the pool. So they're not going to be more diverse because these genes only come from a single individual. They're a sexual. So we're going to cancel it because it is not a true statement. Then we have sexual re producers can easily colonize habitats. Then a sexual re producers. So something to keep in mind is that these a sexually producers, Since they don't need any more maze, they only they can reproduce just whenever they see feed as they don't require additional mates. They have a rapid reproduction rates. And sexually producers do have certain things that they need, such as additional mates. So they have a slower reproduction rate. So we're going to cancel this out because it is an incorrect statement. Then we have both sexual and sexual. Re producers have the same population size as we already established. These sexual re producers have as lower reproduction rate than a sexual re producers. So we're going to say that a sexual Re producers will have a higher population size earlier on in the colonization. So we're going to cancel us out, and it all leaves us with answer choice, A sexual re producers can easily and rapidly colonize habitats. So since a sexual re producers do not need meets and have rapid reproduction rates, they can easily and rapidly colonize new habitats, indifference with sexual reproduces. So we're going to highlight answer choice a as a final answer to our question, I really hope this video helped you, and I hope to see you on the next one.
