4.Show the possible genotypes and phenotypes of the offspring from a cross between a heterozygous male with type A blood and a heterozygous female with type B blood.
Use the information below to answer questions 3-6.
There may be a number of possible alleles for a given gene within a population. In a multiple allele system the dominance relationships between the various alleles must be considered. One of the more familiar examples of a multiple allelic system is that of human ABO blood types. The gene involved codes for a protein on the outside of red bloods cells. Three alleles (IA, IB and i) determine whether the protein is present or absent and the form of the protein present. The A and B alleles code for the A and B forms of the protein and are co-dominant to each other. The O allele (i) codes for no protein and is recessive to both A and B
