Answer 1

Answer #1

Answer is option a.Male A and option e.Male D

Explanation:

Given that mother's blood group is O.Let the genotype be ii(no antigens present)

And the child's is blood group A,then the genotype will be either AA or Ai.

*Possible blood groups of children of male A(blood group A-genotype Ai or AA) with a women of O blood group are

ii,Ai------>O and A blood groups

*Possible blood groups of children of male B (blood group B -genotype BB or Bi) with a woman of O blood group are

ii,Bi----->O and B blood groups

*Possible blood groups of children of male C (blood group O-genotype ii) with a woman of O blood group are

ii------>O blood group

*Possible blood groups of children of male D(blood group AB-genotype AB) with a woman of blood group are

Ai,Bi----->A and B blood groups

So ,there are only 2 chances,either Male A or Male D is the father of the child.
