Humans can have red blood cells that are of type A (IA), type B (IB), or type O (i). These three different alleles can be combined in different ways following Mendel's Laws of Inheritance. The resulting genotypes make either type A, type B, type AB, or type O blood. Type A blood is a combination of either two A alleles (IA IA) or one A allele and one O allele (IAi). Similarly, type B blood is coded for by either two B alleles (IB IB) or one B allele and one O allele (IBi). What pattern of inheritance is human blood type? * incomplete dominance inheritance
codominance inheritance
multiple alleles inheritance
polygenic inheritance
