Question

A child with blood group "O" has "B" blood group type father then the father has genotype of:
A) iOiO
B) iOiB
C) iBiB
D) iAiA

Answer 1

B) is the answer ioib

Answer 2

Heya,

If a child have blood group "O" then both mother and father should have one allele as O bcz O is recessive character in the blood and if the blood group is O then it means that the blood group should be homozygous. So, the father having one allele as 'B' should have one allele of 'O'.

So, the answer of this question will be (2) option i.e. iOiB.

Hope this helps....:)
