Answer: A gene pool is the collection of different genes within an interbreeding population. The concept of a 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. It includes both genes that are expressed, and those that are not.
A population that has a large and diverse gene pool tends have increased biological fitness and is usually able to adapt to and survive throughout pressures caused by rapid changes in environmental conditions or disease. Although individuals may die in such situations, a diverse population often contains enough genetic variation so that there will be an availability of suitable genes that are necessary for survival. This is the basic concept behind the theory of natural selection.
