A genetic study conducted over multiple generations found that the frequency of genotypes in the first generation were AA: 0.36, Aa: 0.48, aa: 0.16. In the second generation, genotype frequencies shifted to AA: 0.16, Aa: 0.48, aa: 0.36. According to the Hardy-Weinberg equilibrium, we can assume: Question 4 options: a. random mating has altered gene frequencies. b. the large size of the population possibly shifted the gene frequencies. Hardy-Weinberg equilibrium requirements are met c. mating in this population must be nonrandom mating.

00:01 Hello students.

00:02 Today's question is about a genetic study that was conducted for few generations and they found the frequency of genotypes in first generation as well as a second generation.

00:12 So in first generation we can see that this is homozygous dominant and this is heterozygous and this is homozygous and recessive.

00:20 And taking a look at its genotype frequency, it is 0 .36, 0 .48 at 0 .61 respectively.

00:27 But here we can see that in a second generation the frequencies in homozygous dominant and recessive have changed so the frequencies of a frequencies of a homozygous dominant dominant and and recessive have changed recessive have changed so question is about according to the hardy -wainburg rule, we have to assume what is going on, what is going on.

01:01 So if their frequencies have changed, it indicates that, it indicates that allele frequency must be changed.

01:10 Allel frequency must be changed.

01:13 Must be changed.

01:15 So there must have been some kind of mutation or gene flow.

01:18 There must have been some kind of gene flow, mutation or anything.

01:23 So that must have changed the little frequency.

01:26 So this while it the so this does not actually go with the go with the hardy -weinberg equation or hardy -weinberg rule.

01:36 Hardy -weinberg rule.

01:39 So hardy -weinberg rule states that in large population, large population there is no mutation, no mutation...
