When father is Rh positive and mother is Rh negative what type is the child?

Answer 1

It depends on the genotype of the parents: If they are AO and BO the child could be all of the 4 ABO-Bloodtypes: AO (= bloodtype A) BO (= bloodtype B) AB (= bloodtype AB) OO (= bloodtype O) If they are AA and BB the child could only be bloodtype AB If they are AO and BB the Child could be AB, or B (BO) If they are AA and BO the child could be AB or A (AO) In short, when the genotype is not given, the child can have any of the ABO-Bloodtypes

Answer 2

If you draw out a punnet square, you will see that the baby can have either group A or B blood (since they can inhereit either A or B from the mother and will not inherit A or B from the father).

The infant could be either Rh+ or Rh- depending on whether the father is homozygous for the D antigen (DD) or heterozygous (Dd).

Answer 3

Need more information to answer correctly...Rh (rhesus factor) is either Rh- or Rh+. For example: my blood type is O with Rh- or O- (O negative) and my husband's is A+ (A positive)..my son's blood type is A+. I had to get Rhogam injections throughout pregnancy to protect my son because of Rh incompatibility. If the mother has a + Rh, there is no need for concern regarding this, only when mother is A-, B-, AB-, or O- AND father is A+, B+, AB+, or O+....It's very important to know, especially if this is not your first pregnancy. Rh incompatibility usually does not affect first pregnancies, but RhoGam is given to mother after delivery to protect the next pregnancy...

Answer 4

This answer depends on the genotype of the father. If he is Rh positive, he will either be heterozygous (Rr) or homozygous dominant (RR). If he is homozygous dominant the child will definitely be Rh positive. The Punnet square would look like this:

mother: ___r___ r

father:

R _______Rr___ Rr

R _______Rr___ Rr

So all children would be heterozygous, but still the positive would show because positive is dominant.

If the father was heterozygous then the children would have a 50% chance of being Rh positive or negative. So theoretically half of the offspring would be Rh positive and the other negative. The Punnet Square looks like so:

mother:____r___ r

father:

R ________Rr__ Rr

r ________rr___ rr

So, to answer your question. We don't know!

Answer 5

Could be either A positive or B positive as the O genes are recessive; and the rh will be positive also

Answer 6

There is no way to tell from that information. All that can be said for sure is that the child will not be O-group.

Answer 7

A negative or B negative. The child cannot be type O or type AB.

Answer 8

The children will have either A blood or B blood, heterozygous.

Answer 9

A OR B
