If a man has type AB blood and his wife has type A blood, can they have a child with type B blood?

Question

If a man has type AB blood and his wife has type A blood, can they have a child with type B blood?

Answer 1

YES -

Man is AB

Wife is AA or AO, if AO then the child can receive B from the father and O from the mother giving BO =group B.

Answer 2

Yes.

Answer 3

yes

because it depends on chance and hetrozygous and homozygous type A

AB*AA=50%AB AND 50%AA

AB*Ai=50%A , 25% B and 25%AB

Answer 4

yes but only if one of his wife's chromosomes contain a recessive A blood type. there's a 1 in 4 chance if this is the case. If she doesn't, then no

XA Xa

                 could produce XB Xa and this would be a B!

YA XB

Answer 5

Yes, it depends on recessive or dominance :]

Answer 6

If the wife has AO then it is possible, if she has AA, then it is impossible.  And here's why:

Husband will be the vertical, Wife will be horizontal, and the 4 groups between will show the possible outcomes of the children's blood type.

     A    A

A AA  AA

B AB  AB

or

     A     O

A AA  AO

B AB  BO

Hope that helps

Answer 7

yes, it is possible. they have like a 25% chance if the wife has AO blood but if she has AA blood there is no chance

Answer 8

She could have an affair....just kiddin, yes its possible.

Answer 9

no, the child must have the same blood group of one of its parents,

Answer 10

If the man has AB blood then he presents both alleles for type A and type B blood, his genotype would be I^a I^b (AB). If the woman has type A blood she can either have two alleles for type A blood or one allele for type A blood and one allele for type O blood. Her genotype could either be I^aI^a (AA) or I^ai (Ao)

So yes, they could but it depends on whether or not the woman is heterozygous or homozygous for type A blood. If she is heterozygous then there is a change that she passes on the type O allele and the father passes the type B allele, and since O is recessive then type B blood would be presented in the child.

Answer 11

depends if the A blood is recessive or dominant. if it's dominant then probably not. if it is recessive then the B blood is probably in the line of their geneology and it is a possibility that their child could have type B blood.
