Video transcript

Hello everyone and welcome to today's video and the absence of factors that are responsible for evolution. The A leo and genotype frequencies in a population remain constant by the hardy Weinberg law, which of the following is the frequency of the hetero cycles individuals in the hardy Weinberg equation. Remember that this equation is going to be p square plus two PQ plus Q square is equal to one here. This p square is going to be the frequency of the homo zegas dominant individuals. This Q square is going to be the frequency of the hormones I guess Recessive individuals and these two PQ is going to be the frequency update heterocyclic individuals. So these two P. Q. Is going to be the answer to our question, which is going to be answer choice D. I really hope this video helped you and I hope to see you on the next one.
