A woman with type O blood is expecting a child. Her husband is type A. Both the woman's father and her husband's father had type B blood. What is the probability that the child will have type O blood?
a)25% B) 50% C) 75% D) 100%
Answer:
B) 50%
Explanation:
The father of the husband has blood type B. This means that the husband cannot be homozygous for IA allele and has genotype IAi. The genotype of the woman with respect to blood type O will be "ii".
A cross between IAi and ii would produce progeny in following phenotype ratio= 1/2 blood type A: 1/2 blood type O
Therefore, there are 50% chances for this couple to have a child with blood type O.
