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. WebHence, alleles I A and I B are dominant over the allele i. As we know, each diploid organism bears two pairs of alleles. Hence, in humans, there are two types of alleles of any …

Traits controlled by a single gene with more than two alleles are called multiple allele traits. An example is ABO blood type. Your blood type refers to which of certain proteins called antigens are found on your red blood cells.
WebSep 26, 2024 · There are traits in humans and other organisms that have three or more different types of alleles (genes). When a trait has three or more distinct alleles, we refer to it as having multiple alleles inheritance.
