Detailed explanation-1: -A gene pool is the sum of all the alleles (variants of a gene) in a population. Allele frequencies range from 0 (present in no individuals) to 1 (present in all individuals); all allele frequencies for a given gene add up to 100 percent in a population.

Detailed explanation-2: -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-3: -The collection of all the genes and the various alternate or allelic forms of those genes within a population is called its gene pool.

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.
