What is meant by allele frequency?

1 Answer

Allele frequency is the frequency of an allele relative to that of other alleles of the same gene in a population.


An allele can have a frequency of #0->1#.

If it is #1#, then all organisms in a population are homozygous (for this particular allele). When this occurs, genetic diversity is reduced and the allele is said to be 'fixed'.
