WebAn example is the human ABO blood group system; persons with type AB blood have one allele for A and one for B. (Persons with neither are type O.) Most traits are determined … WebJun 16, 2024 · Plural alleles among humans. There are traits by humans and select organisms that have three or more different types of alleles (genes). When a trait have three or more distinct alleles, we refer to it as having multiple alleles inheritance. The human ABO blood type alleles/trait is einer example of a trait with multiple allele-specific.

WebAn allele is a gene variant present at the locus of a gene that codes for a specific trait. In Mendelian genetics, there are two kinds of alleles - dominant and recessive. In non-Mendelian inheritance, there are several more kinds of alleles; incompletely dominant, codominant, and more. Some alleles are located on autosomes and others on sex ...
