Detailed explanation-1: -A gene pool refers to the combination of all the genes (including alleles) present in a reproducing population or species.

Detailed explanation-2: -The combination of alleles that an organism carries constitutes its genotype. If the paired alleles are the same, the organism’s genotype is said to be homozygous for that trait; if they are different, the organism’s genotype is heterozygous.

Detailed explanation-3: -Allele Frequency In population genetics, the term evolution is defined as a change in the frequency of an allele in a population. Frequencies range from 0, present in no individuals, to 1, present in all individuals. The gene pool is the sum of all the alleles at all genes in a population.

Detailed explanation-4: -Since there are two copies of each gene, there are two alleles, which may be the same or different.

Detailed explanation-5: -The dominant allele is always the most common allele in the gene pool.
