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: -Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.
Detailed explanation-3: -The gene pool is the sum of all the alleles at all genes in a population.
Detailed explanation-4: -Populations evolve through genetic change. A population’s gene pool includes all the alleles of all the genes of all the individuals within it. A gene pool for a single gene includes all the alleles of that gene present in all individuals. Analysis of a gene pool can reveal variation which is not visible in phenotypes.
Detailed explanation-5: -Genetic Variation in Populations A population is a group of individuals that can all interbreed, often distinguished as a species. Because these individuals can share genes and pass on combinations of genes to the next generation, the collection of these genes is called a gene pool.
