Video transcript

Hello, everyone. And in today's video we have the following problem. The chance of a species going extinct is decreased by moving members of the species from angiography region to one other due to an increase. And and so were given different processes that we need to identify from. However, let us visualize what is happening here in this scenario before we jump into solving a problem. So we have just members of the same species that are rotating from one region to another. So let's say that members in region one have a leo's, A. B. C. Or in upper case. And members of region to have a leo's abc as well. All in lower case as these members from region one move into region to They're going to introduce new leo's to the population in Region one. And the same thing will happen here. Since Newell eels are being introduced into the population is going to lead to an increase in the levels of genetic diversity of each population. Right? And so the increase in genetic diversity. This introduction of leo's is going to make each population more resilient to change. They're going to make them less likely to go extinct since they have the adaptations necessary to survive a wider range of change. And so that is why answer choice. A increasing genetic diversity is going to be the final answer to our problem. I really hope this video helped you and I hope to see you on the next one
