WebSep 21, 2014 · Sep 21, 2014 Having more than 1 or 2 alleles for a trait can greatly increase the number of phenotypes, depending on the trait's specific pattern of inheritance. For example, human blood type is controlled by 3 alleles (just referring to the ABO blood groups here): A, B, and O. A and B are both dominant to O but they are codominant to each other. WebThe frequencies of all the alleles of a gene must add up to one, or 100%. Allele frequency is different from genotype frequency or phenotype frequency. Genotype and phenotype frequencies can also be calculated and are important for understanding how populations evolve, but they are not the same thing as allele frequency.
