Consider a population in which the frequency of allele A is p=0.7 and the frequency of allele a is q=0.3 and where the alleles are codominant. What will be the allele frequencies after one generation if the following occurs?

wAA=1, wAa=0.99, waa=0.98

Hello everyone and welcome to today's video to consider a pea plant population of 100 plants where the a leo's for yellow color pots are dominant over green color pots. According to the observation, there are 49 green color pot plants. Find the audio frequencies using the hardy Weinberg equation. Remember that this equation is going to look like this P square plus two PQ plus que square is going to be equal to one and this Q square is going to be representing the homo zika's recessive individuals which were told in the problem that there are 49 green pot plants. So there are 49 home mosaic resistive individuals out of 100. So Q square is going to be equal to 0. which is a frequency of homo cycles. Recessive individuals in the population. If we take the square root of each side, we're going to see that Q is going to be equal to 0.7. Now, if we take the square root of this equation on both sides, we're going to see that P plus Q is going to be equal to one. We already know that Q is 0.7. We already have the a leo frequency of the recessive values. However, we don't know the dominant ones but we can use this equation to find it. We have that P plus 0.7 is equal to one and then we have that P is equal to one minus 0.7. P is equal to 0.3. So que we found that it was 0.7 p. We found that it was 0.3. These are the legal frequencies of the population in terms of the dominant and recessive helios. So the correct answer choice for this question is going to be answer choice. I really hope this video helped you and I hope to see you on the next one.
