is a change in the frequency of gene variants, or alleles, in a population, typically occurring over a relatively short time-period.

is the field of biology that studies allele frequencies in populations and how they change over time.

refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of the gene.

The gene pool of a population consists of all the copies of all the genes in that population.

A population is a group of organisms of the same species that are found in the same area and can interbreed. A population is the smallest unit that can evolve—in other words, an individual can’t evolve.

Mathematical equations that describe allele frequencies in a population that is not evolving. It assumes no mutation, migration, selection, or genetic drift.
