What are the possible phenotypes of the children if the mother has Type O blood and the father has type AB blood

Type A

Type B

Explanation:

Blood type in humans is controlled by a gene with multiple alleles. Alleles iA and iB are dominant over allele i but are codominant. This means that the following genotypes will give rise to the phenotypes as follows:

iAiA or iAi - type A

iBiB or iBi - type B

iAiB - type AB

ii - type O

According to this question, if a mother with Type O (ii) blood and a father with type AB (iAiB) blood are crossed, the following offsprings will be likely produced:

iAi, iAi, iBi, iBi

iAi - type A

iBi - type B

Hence, the possible phenotypes of the children will be type A and type B blood.
