Nail Patellar syndrome shows autosomal dominant inheritance. N = affected; n = normal The ABO blood group gene has 3 alleles: IA = A allele; IB = B allele; i = O allele. The IA and IB alleles are codominant. The IA and IB alleles are both completely dominant over the i allele. The two genes are located 10 map units apart. Greg has the genotype NIA/ni (N__IA  n__i) Susan has the genotype Ni/nIB (N__i  n__IB) What is the probability that their child will have a normal phenotype and blood type B?
