Question

Assume that the flower population described in the previous problem undergoes a different pattern of predation. Flower-color determination and the starting frequencies of C₁ and C₂ are as described above, but the new insects attack yellow and red flowers, not orange flowers. As a result of the predation pattern, the relative fitness values are C₁C₁ = 0.40, C₁C₂ = 1.0, and C₂C₂ = 0.80.

What are the allele frequencies after one generation of natural selection?

Accepted Answer

Hello everyone and welcome to today's video. So suppose that in a population of spider, the is dominant over the gray A. If the frequency of the is 70% what is the frequency of the hetero genotype? Assuming that the population is under Harley Weinberg equilibrium? So as answer choice A we have 50% as answer choice B, we have 70% as answer choice C we have 42%. And as answer choice D we have 35%. So according to the Hardy Weinberg equation P or the frequency of the dominant allele plus Q or the frequency of the process is going to be equal to one. Now, we are told that the black A or the dominant ale which is P is going to have a frequency in the population of 70% or 0.7. So 0.7 plus Q is going to be equal to one. We know that Q or the frequency of this recessive ali is going to be 0.3. Now, in the problem, they're asking us for the frequency of the heterozygous genotype. And according to the Hardy Weinberg equation, which can also be represented like this. It is going to be these two times P times Q, we already determined that Q is 0.3. In the problem, we are told that P is 0.7. So all we have to do is multiply two times 0. or 0.7 times 0.3. And we're going to obtain this frequency of the heterozygous genotype, which is going to be 0.42 or 42%. So the correct answer for this question is going to be c 42%. I really hope this helped you and I hope to see you on the next video.
