Question

Two populations of deer, one of them large and living in a mainland forest and the other small and inhabiting a forest on an island, regularly exchange members that migrate across a land bridge that connects the island to the mainland.

In which population do you expect to see the greatest allele frequency change? Why?

Accepted Answer

Hey, everyone. Let's take a look at this question together in a population of men. 150 suffer from hemophilia. Determine the frequency for the hemophilia allele carried on the X chromosome. Is it answer choice? A 0.15, answer choice B 0.25, answer choice C 0.3 or answer choice D 0.5. Let's work this problem out together to try to figure out what the frequency is or that hemophilia allele. So in this population, we have a total of 600 men and of those 600 men, 150 are suffering from hemophilia. So that means that 150 out of 600 total men suffer from hemophilia. And we want to determine the frequency for the hemophilia allele. So we divide 150 by 600 which gives us a total of 0.25, which is the free frequency of the hemophilia allele in this population. So answer choice B is the correct answer. Since that allele frequency can be calculated by taking the number of suffering individuals, which is 100 and 50 divided by the total number of the population which is 600 we get 0.25. I hope you found this video to be helpful. Thank you and goodbye.
