Question A, B, O blood types in humans demonstrate the phenomena known as co-dominance. The blood Rh factor (+ or -) displays an inheritance pattern of simple dominance. Using the following designations: A as the dominant allele for blood type A, B as the dominant allele for blood type B and o as the recessive allele for blood type O and R as the dominant (+) Rh allele and r as the recessive (-) Rh allele, what are all of the possible genotypes for the following blood types. a) A+
b) O+
c) B-
d) AB-
e) If one parent has the blood type A+ and another parent has O+ blood, what are the possible blood types of their children?
