Answer:
In humans, blood group is determined by three alleles
,
, and
.
and
are co-dominant whereas
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
allele.
The genotype of other person can be
,
, or
.
There is only one condition in which the person can have offspring with blood group O that is, when the other parent is
.
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%.
