mary has type a blood. her son bill has type ab blood. which blood type does bills dad have if he is homogenous for blood type?\na\nb\nab\no
Answer
Brief Explanations:
Blood type A can have genotypes AA or AO. Blood type AB has genotype AB. Since Bill has type AB blood and Mary has type A blood, and Bill's dad is homogenous. Mary must have contributed an A - allele. For Bill to have AB blood, his dad, being homogenous, must contribute a B - allele. So the dad has homogenous B blood type (BB).
