## What are the possible blood groups of a child whose parents have blood group A and B?

A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).

## What will be the blood type of the offspring if his her parents have different blood type?

While a child could have the same blood type as one of his/her parents, it doesn’t always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B. But two O parents, for example, will pretty much always have O kids. They will match both parents.

What are the possible blood groups of a child whose parents are heterozygous for A and B blood group?

AABAAO=blood type A.

• AABOAO=blood type A.
• BABAAO=blood type AB.
• BABOAO=blood type B.
• ### What are the possible blood types of a child with 2 parents that are both type AB blood?

For instance –

• Mother with AB blood type can either pass the A or B allele to the baby.
• If both parents belong to the blood group O, the child will also belong to the O blood group.
• Two A blood group parents can give their child either A or O blood group.

### Which of the following is are possible blood types of the children of an A+ mother and O+ father?

That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type. Each of their kids will also have a 3 in 8 chance of having A+, a 3 in 8 chance of being O+, and a 1 in 8 chance for being A-. An A+ parent and an O+ parent can definitely have an O- child.

Do brothers and sisters have same blood?

Each biological parent donates one of their two ABO alleles to their child. Identical twins will always have the same blood type because they were created from the same fertilized egg (fraternal twins can have different blood types — again, providing the parents do — because they are created by two fertilized eggs).

#### Is it possible for twins to have different blood types?

Dizygotic (fraternal) twins may have the same blood type, or they may have different types. Therefore, it may be concluded that twins with differing blood types are dizygotic, or fraternal. However, twins with the same blood type can be either fraternal or identical.

#### Can two different blood types have the same child?

For example, parents with AB and O blood types can either have children with blood type A or blood type B. These two types are definitely different than parents’ blood types! But two O parents, for example, will pretty much always have O kids. They will match both parents.

What is the blood group if both parents are homozygous?

If both the parents are homozygous (I A I A x I B I B) , all of their children will have AB blood group. But if father is heterozygous (I A I O ”) and mother is homozygous (I B I B ); the total different types of possible combinations by three alleles (I A, I B and I O) will be (I A I B and I B I O ).

## What blood type would a child of AB and oo be?

Now, you can see a situation where the child’s possible blood type combos are unlike either of the parents. The child of an AB dad and a OO mom could either be AO (blood type A) or BO (blood type B). You could do a Punnett square for every possible combination of parent blood types.

## How can I Find my Child’s blood type from my parents’ genes?

All we need to know are the parents’ blood genotypes. Using a Punnett square is a great way to figure out a child’s possible blood types based on the parents’ blood types. A Punnett square is just a diagram that helps to organize all of the genes to figure out the likelihood for a certain combination of genes.
