Answer:
Type A
Type B
Step-by-step 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.
