WebAlthough individual humans (and all diploid organisms) can only have two alleles for a given gene, multiple alleles may exist at the population level such that many combinations of two alleles are observed. WebHuman blood type is determined by codominant alleles. There are three different alleles, known as I A, I B, and i. The I A and I B alleles are co-dominant, and the i allele is recessive.

WebAs we know, each diploid organism bears two pairs of alleles. Hence, in humans, there are two types of alleles of any combination. Depending on the combination and dominance of allele blood type of an individual could be determined. The different combination of alleles and their type of blood groups are given below.
