Complete the following chart and rewrite it: Genotype Phenotype I A I A or I A i _____ _____ B I A I B _____ _____ O

Genotype Phenotype I A I A or I A i A I B I B or I B i B I A I B AB ii O Human 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 codominant, and the i allele is recessive. The possible human phenotypes for the blood group are type A, type B, type AB, and type O. Type A and B individuals can be either homozygous (I A I A or I B I B , respectively), or heterozygous (I A i or I B i, respectively).
