How many alleles affect human blood type
WebThe alleles can be shown as W for white and B for black. There are three possible genotypes: WW, BB and BW. There are also three possible phenotypes: WW = white, BB = … 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.

WebHundreds of versions (alleles) of the HLA-B gene are known, each of which is given a particular number (such as HLA-B27 ). Closely related alleles are categorized together; for example, more than 60 very similar alleles are subtypes of HLA-B27. These subtypes are designated as HLA-B*2701 to HLA-B*2763 .
