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 frequency is how often an allele occurs in a gene pool relative to the other alleles for that gene. Look at the example in the Table below. The population in the table has 100 members. In a sexually reproducing species, each member of the population has two copies of each gene.

Detailed explanation-4: -… A gene pool refers to the combination of all the genes (including alleles) present in a reproducing population or species. A large gene pool has extensive genomic diversity and is better able to withstand environmental challenges.

Detailed explanation-5: -An allele frequency is calculated by dividing the number of times the allele of interest is observed in a population by the total number of copies of all the alleles at that particular genetic locus in the population. Allele frequencies can be represented as a decimal, a percentage, or a fraction.
