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 genotype frequencies among the progeny of predation survivors?

Accepted Answer

Hello everyone and welcome to today's video. So in a population of beetles, the blue Ali for capital B dominates over the black ale which is case B. So if the frequency of the black allele is 40% what is the frequency of the homocysteine conditions are applied as answer choice A we have 36% as answer choice B we have 50% as answer choice C we have 75%. And as answer choice D we have 25%. Well, in the problem, we are told that the frequency of the black ali is going to be, it is going to be 40%. So Q or the frequency of the recessive ali is going to be 0.40. Now, we know from the Hardy Weinberg equation that P plus Q is going to be one. So if you want to determine the frequency of the dominant Ali, all we have to do is use this value that we're given. So P is going to be equal to one minus 0. P is going to be 0.60. Now, the homo cycles dominant genotype or the frequency of the homo cycles, dominant genotype in the population is going to have a value of P squared according to the Hardy Weinberg equation. So we know that P is 0.60. All we have to do is square this 0.60. And we're going to obtain 0.36 or 36%. So this is the frequency of the B of the capital B, capital B genotype or the homocysteine conditions. So the correct answer for this question is a 36%. I really hope it's helped you and I have to see you on the next one.
