Definition of Genotype Frequency



Genotype frequency is the total number of individuals in a population constituting a particular genotype divided by the total number of individuals that are present in that population. It is expressed in the form of a fraction or a percentage. It can also be defined as the relative frequency of an allele present at a specific locus in a population.

 


The change that takes place in the frequency of alleles over a passage of time in a population is known as microevolution. The allelic frequency is used in order to determine the number of variations at a specific locus and it can be determined from the genotype frequency.
