Question

A mother has blood type AB and a father has blood type O and they have a child together.

8. If blood is needed to be given to the mother and AB blood type is not available, what other blood type(s) can the mother receive (not considering Rh factor)? Explain your answer.

9. Explain why a person with AO genotype has the same phenotype (blood type A) as a person with AA genotype. Pink is the phenotype from the expression of a heterozygous genotype in flowers that exhibit incomplete dominance. Red and white flowers result from the two homozygous genotypes.

Answer 1

Mother can receive blood from all blood types that is A,B,O because it is well known as a universal acceptor it can receive blood from all blood groups because it contains both A and B antigens in there body due to which they is no cross reaction.

Because AO is heterozygous where due to presence of O where it is a recessive allele and A is dominant over O so the AO genotype also shows same pheotype as AA that is A blood group where single allele is enough to express a dominant character.

Where here is an another condition in case of flowers where it is not able to express the dominant nature in heterozygous condition because this is the incomplete dominant case where in this condition the allele ( dominant) is not able to express completely over recessive due to which different phenotype is formed from the homozygous phenotype .
