Marysya12 [62]

Answer:

In humans, blood group is determined by three alleles I^{A}, I^{B}, and i.

I^{A} and I^{B} are co-dominant whereas i is recessive to other two.

Thus, if a person with blood group O produces offspring with blood group B then the other parent must contain I^{B} allele.

The genotype of other person can be I^{A}I^{B}, I^{B}I^{B}, or I^{B}i.

There is only one condition in which the person can have offspring with blood group O that is, when the other parent is I^{B}i.

In this condition, the probability of an offspring to have blood group O is 50%.

In other conditions, the probability of an offspring to have blood O is 0%.
