What will be the blood group of ababy when father has b plus blood group and mother has o plus blood group?

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

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

Answer 6

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.

Answer 7

The child will have bloodgroup B or O
