Ameasurement that determines how often the allele (gene variant) expression of a particular gene arises in a population and is an indication of genetic diversity within a species population;

Allele frequency

Explanation:

Allele frequency can be described as the percentage or ratio for the existence of a particular allele in a population. Allele frequency determines which allele is present more abundantly in a population and which allele is not significantly present in the population. The allele frequency determines the genetic diversity which will be present in a population. The alleles which code for traits that make an organism more adaptable to a particular environment will have an increased allele frequency.
