- A gene pool is the total genetic diversity found within a population or a species. A large gene pool has extensive genetic diversity and is better able to withstand the challenges posed by environmental stresses. Inbreeding contributes to the creation of a small gene pool and makes populations or species more likely to go extinct when faced with some type of stress.

- The collection of genes in an interbreeding population that includes each gene at a certain frequency in relation to its alleles: the genetic information of a population of interbreeding organisms <the human gene pool>.
