Detailed explanation-1: -Complete answer: Gene pool is the sum of a population’s genetic material at a particular time. The term typically is used for a population of individuals of the same species that include all genes and combinations of genes (sum of the alleles) in the population.

Detailed explanation-2: -The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. This also proves to be the basic level at which evolution occurs.

Detailed explanation-3: -Every human has around 20, 000 genes and 3, 000, 000, 000 bases. Your entire sequence of genes and bases is called your genome.

Detailed explanation-4: -Genotype. A genotype is an individual’s collection of genes. The term also can refer to the two alleles inherited for a particular gene. The genotype is expressed when the information encoded in the genes’ DNA is used to make protein and RNA molecules.

Detailed explanation-5: -A gene pool is the collection of different genes within an interbreeding population. The gene pool usually refers to the sum of all the alleles at all of the loci within the genes of a population of a single species. So correct option is A, gene pool.
