Detailed explanation-1: -Allele frequency refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of the gene. The gene pool of a population consists of all the copies of all the genes in that population.

Detailed explanation-2: -4. Relative frequency is the number of times an allele occurs in a gene pool compared with the number of times other alleles for the same gene occur.

Detailed explanation-3: -Allele Frequencies In a sexually reproducing species, each member of the population has two copies of each gene. Therefore, the total number of copies of each gene in the gene pool is 200.

Detailed explanation-4: -Gene pool of a population will consist of a large number of genes which will vary in their frequencies. Gene frequencies are defined as proportions of different alleles of a gene in a population, and in a particular generation these frequencies will depend upon their frequencies in preceding generation.

Detailed explanation-5: -The frequency of the “a” allele. Answer: The frequency of aa is 36%, which means that q2 = 0.36, by definition. If q2 = 0.36, then q = 0.6, again by definition. Since q equals the frequency of the a allele, then the frequency is 60%.
