00:01 The micro evolution, the micro evolution, evolution occurs at, occurs at the level of, at the level of the, of the option c, option c population, population that is the answer of this question.

00:36 Then the next question is, according to the, according to the hardy -wenberg, hardy -wenberg, wenberg equation, equation to characterized, characterized, characterized a population, a population and the exception, in this exception, exception the answer is option b, option b.

01:22 The other statements are exist for that, but the exception is migration, exception is migration, that is the option answer is correct answer of this question.

01:37 Now, the next answer of the question is, let's assume, let's assume frequency of, frequency of r allele, frequency of r allele is 0 .40, means it represent as q and that is the value of the q is 0 .40.

02:08 There are two alleles, there are two alleles, two alleles, capital r and small r and that is p is equal to 1 and q is equal to 0 .40 here.

02:27 Then q is equal to, we can represent if p is 1, then q is equal to 1 minus 0 .40.

02:35 Now, expected frequency, expected frequency, expected frequency of heterozygous, heterozygous individual, individual and heterozygous means it is, it should be capital r and small r and that is represent as 2 p q and now p is equal to 0 .60 and q is equal to 0 .40.

03:13 So, now we have 2 into 0 .60 and then the value is q, q is the multiply by 0 .40.

03:24 By solving this we get the answer 0 .48.

03:28 So, option c, so option c is correct answer, is correct answer, answer...

Question

Select one or more: a. the initial frequency of the allele to be high. b. the allele to be recessive. c. the population size to be small. d. chance (genetic drift) to influence which allele is fixed.
