Allele frequency

from Wikipedia, the free encyclopedia

Allele frequency (or allele frequency ) is a term of population genetics , the relative frequency of an allele in a population referred. It is calculated by dividing the number of copies of a given allele by the total number of copies of all alleles present in the population.

One speaks of the gene frequency (also gene frequency ) when the frequency calculation does not refer to the total population, but to the genome of an individual .

Evolution occurs when the frequency of allele changes in a population . Possible causes for this are natural selection (changes the frequency of individual alleles) or genetic drift .
