The child can be A, B or AB. The only group the child shouldn't be is O.

You receive one allele from each parent. Each group actually has two places. Therefore the B is actually BO or BB.

If child is A, this means the mother's group is BO.

Now mix and match.

Mother gives B Father gives B Child is B

Mother O Father B Child B

Mother O Father A Child A

Mother B Father A Child AB

Mother B Father B Child B

The Rh factor is similar but not so easily determined. While it also has two places, the + can hold a - for it's second placement +-

For instance, my mother is AB Neg but all of her children are Pos. This means her Rh factor must be -+.

Hope this helps.

It will depend on whether the father is heterozygous, BO, or homozygous BB. If he is heterozygous the child could have blood type B or O. If he is homozygous then the child will have blood type B.

If both parents are heterozygous Rh+Rh-, then there is a 75% chance the child will be positive, and a 25% chance it will be negative. If either parent is homozygous, Rh+Rh+, then the child must be positive.

There will be a 50% chance that the baby will have type B blood, and a 50% chance that the baby will have type O blood.

If one parent is B Negative and one is A Positive, the baby can be A Positive, A Negative, B Positive, B Negative, AB Positive, AB Negative, or possibly O Positive or O Negative.

if father blood group is homozygous (BB)

then all kids will have B blood type

if father blood group is heterozygous (Bi)

then 50% will be O and the other 50% are B

A child of parents with A+ and B+ blood can have A, B, AB, or O with Rh+ or Rh-.

So the child has a chance to have any blood type with that combination.

A or AB

### Could a father with a blood group ab have a child that is O blood group?

Absolutely. A child will either have its mother's blood type or its father's blood type. If the mother's blood type is NOT O, then someone else is the father.

### Can a mother of o blood group have a healthy child with a father o?

can a mother of o blood group have a healthy child with a father type o

O

ab

95% not.

### Can a mother with blood group O and gather blood group AB produce O blood group child?

Yes, it is possible for a mother with blood group O and a father with blood group AB to have a child with blood group O. This would occur if the child inherited the O allele from the mother and the O allele from the father.

No

### How does a A blood type mother AND a father have a -0 blood type child?

The mother and father both have heterozygous alleles for the blood group A. The blood group A can have the alleles AA or AO, when both parents are AO, there is a one in four chance that the child will have blood group O as this blood group is recessive.

### If mother is A negative blood group and the child is A positive blood group what is the father's likely blood group?

Probably more than likely A+. Because the +Rh gene is usually dominate. Take for instance- Mother is A+, Child is A=. Father is A=, In this instance the father has the dominate gene for the absence of the Rh antigen on the redcell. The mother is recessive.

### If a mother is B positive blood group and a father is O negative blood group can they have a child that is O positive blood group?

yeah its possible.

### What blood group will the baby have if mother is o and father is blood group ab?

The child could either be blood type A or blood type B.
