What is the genotype of a person with type A blood, who had a father with type O blood? IAIB
IAIA
IAi
ii

IAi

Explanation:

Blood group in humans is controlled by three alleles namely: iA, iB and i. Alleles iA and iB are dominant over allele i but are co-dominant over one another. The following genotypes with their following blood group are:

iA - blood type A

iB - blood type B

iAiB - blood type AB

i - blood type O

In this case, an individual with type A blood had a father with type O blood. This means that the genotype of the individual will be iAi because the person will inherit the "i" allele from the father but since the "iA" allele is dominant, the type allele will be expressed.

answer; i believe that the correct answer is(d) nondisjunction during meiosis;
