Answer
The correct answer would be B) 50 %.
In humans, the blood group is determined by three alleles [tex]I^{A},I^{B},[/tex] and [tex]i[/tex].
[tex]I^{A} and I^{B}[/tex] are co-dominant whereas [tex]i[/tex] is recessive to other two.
Thus, the genotype of a person with blood group O would be [tex]ii[/tex].
The genotype of a person with blood group B would be either [tex]I^{B}I^{B}[/tex] (homozygous condition) or [tex]I^{B}i[/tex] (heterozygous condition).
The crosses are shown in the image below.
There is only one condition in which the person can have offspring with blood group O that is, when the other parent is [tex]I^{B}i[/tex].
In this condition, the probability of an offspring to have blood group O is 50%.
In other condition, the probability of an offspring to have blood O is 0%.
