A gene pool is a collection of all the alleles or the variants of genes in a population.

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.

Key Points

• A gene pool is the sum of all the alleles (variants of a gene) in a population that can pass on combinations of genes to the next generation.

Key Terms

gene pool: the complete set of unique alleles that would be found by inspecting the genetic material of every living member of a species or population

alleles: one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

gene: a section of DNA that codes for a characteristic
