Detailed explanation-1: -Allele frequency (also called gene frequency) is the term used to describe the fraction of gene copies that are of a particular allele in a defined population.

Detailed explanation-2: -A gene pool is a collection of all available genes and their alleles in a population (unit of evolution).

Detailed explanation-3: -A gene pool is the sum of all the alleles (variants of a gene) in a population.

Detailed explanation-4: -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.

Detailed explanation-5: -1 = p2 + 2pq + q2 P and q each represent the allele frequency of different alleles. The term p2 represents the frequency of the homozygous dominant genotype. The other term, q2, represents the frequency of the homozygous recessive genotype.
