Correct answer: B
The correct answer is Option B: A-IV, B-II, C-III, D-I.
Here's the breakdown of each term and its corresponding definition:
(A) Gene pool: This refers to the total number of genes and their alleles within a population. So, the correct match for gene pool is (IV) Total number of genes and their alleles.
(B) Genetic drift: It's a random change in the frequency of alleles within a population due to chance events like natural disasters or small population size. Therefore, the correct match for genetic drift is (II) Change in gene frequency by chance.
(C) Gene flow: This involves the movement of genes between populations. It can occur through migration or the exchange of genetic material. So, the correct match for gene flow is (III) Transfer of genes into or out of population.
(D) Gene frequency: It represents the relative proportion of a specific allele within a population. Gene frequencies tend to remain stable within a generation unless acted upon by evolutionary forces. Therefore, the correct match for gene frequency is (I) Stable within a generation.
