No. A and B are dominant and O is recessive. Here are possibilities that can occur:

AB and BO

---------------

A B

B AB BB

O AO BO

AB and BB

---------------

A B

B AB BB

B AB BB

Can a man with blood type b and a woman with blood type ab have a child with blood type b?

Yes, a man with blood type B and a woman with blood type AB can have a child with blood type B. The child would inherit one allele for blood type B from the father and either an A or B allele from the mother. The child's blood type could be either B or AB.


Is it possible for a woman with AB blood and a men with type B blood to have children with type A?

YES! If the woman has type AB blood type andthe man has type BO blood tye it is possible for them to have a child with AO blood type which registers as type A. It is rare though. Genetics tell us that they have a 50% chance of a baby with type B blood and a 25% chance of a baby with type AB blood. That means that they have a 25% chance of having a baby with type A blood. Remember this doesnt account for positive or negaive antibodies.


A man heterozygous for blood type A marries a woman heterozygous for blood type B The chance that their first child will have type O blood?

There is a 25% chance that their first child will have type O blood if both parents are heterozygous for blood type A and B. This is because the child could inherit an O gene from each parent, resulting in blood type O.


A father has type O blood and the mother has type AB blood What percent of the offspring should have type A blood?

A woman with type AB blood has both alleles that give blood both the A antigens and the B antigens, but the man with type O blood has both of the alleles that lack these antigens. Because the child will receive one allele from the mother and one from the father, none of their children will have AB or O blood.


Can a woman with type ab blood have a child with type o?

NO. Not at all. Each parent has an A or a B to contribute to the child. Therefore, the only possibilities for the child are: An A from each parent (making it an A) A B from each parent (making it a B) and An A from one, and a B from the other, (making it an AB). This a super-simple answer. For more detail on ABO blood grouping, type in ABO on wiki. NO. Not at all. Each parent has an A or a B to contribute to the child.
