If a heterozygote mates with another heterozygote, there is 75 % chance passing the gene on and only a 25 % chance that the gene will be displayed.

If two alleles of a given gene are identical, the organism is called a homozygote and is homozygous with respect to that gene ; if instead the two alleles are different, the organism is a heterozygote and is heterozygous.

If there are two alternative phenotypes, by definition the phenotype exhibited by the heterozygote is called " dominant " and the " hidden " phenotype is called " recessive ".

If there are more than two different allelic forms, the frequency for each allele is simply the frequency of its homozygote plus half the sum of the frequencies for all the heterozygotes in which it appears.
