Model answers: Co-dominance & Multiple Alleles
How many different alleles are there in the six genotypes? Three Which are the alleles in human blood groups which show co-dominance? IA and IB Suppose that Adam was heterozygous for blood group A, with the genotype IAi, and Eve was heterozygous for group B and had genotype IBi. Would it be possible for their children to have all the blood group genotypes found in the modern human population (shown above)? Explain...
