A man having blood A is married with an having blood group B. Work out the genotype of a man and woman if their of the children is born with blood group O. What is the possible genotype of other offsprings.

Explanation

If man is homozygous `-I^(A)I^(A)` and woman is also homozygous `-I^(B)I^(B)` then the offsprings will be `-I^(A) I^(B)`
If the man is heterozygous -`I^(A) I^(i)` and the woman is also heterozygous - `I^(B)I^(i)` then the following will be

Thus, the genotypes of parents are as follows : Man `=I^(A)I^(i)` Woman = `I^(B) I^(i)`
and the genotypes of offspring are - `I^(A) I^(B),I^(A)I^(i), I^(B)I^(i) and I^(i)I^(i)`
