YES. Blood type is determined by two alleles. An "A" individual can be homozygous "AA" or heterozygous "AO" and still be considered type A. The same is true of a "B" individual. If the father is "AO" and the mother is "BO" then statistically, they have a 25% chance of having a child that is "OO" or type O.

Blood type can be O positive, A positive, B positive, AB positive, O negative, A negative, B negative or AB negative.

O positive, A positive, B positive and AB positive can be collectively described as Rh positive. Rh stands for Rhesus.

Two O positive parents will definitely have an O positive baby. Parents and baby could all also be described as Rh positive.

No. That dad should be SUSPICIOUS because there's no WAY that he's the biological dad.

It's clear from just looking at the ABO blood groups. O's are recessive in this case. If you're an O type, your genotype must be O-O. If you're an A type you can be heterozygous, A-O, or homozygous A-A.

If you cross the two parents, both (homozygous) O's, it'll look like this:

.......mom...IO.......IO

dad

IO..............IOIO....IOIO

IO..............IOIO....IOIO

There is NO A. To make an A type baby with an O type mom, the dad must be heterozygous A for a 50% chance or homozygous A for a 100% chance.

No, it isn't possible to have a child without the RH factor if both parents carry the gene for RH.

Rh positive mother a positive baby?

If a person has the Rh factor, then they are positive. If they don't have the Rh factor, they are negative. The Rh factor is dominant, so a mother with it would have an Rh positive baby even if the father is negative for the Rh factor.


Can an o negative father have a baby b positive while mother is ab positive?

I am no professional so I may be wrong, but normally the child takes after their father so I think the child will be an O negative.


Father has b positive and mother o negative can the baby be a negative?

No, the baby cannot be A-. A and B genotypes are codominant and O is recessive. Since the father is B and not AB, his genotype must be either BB or BO. The mother is OO. So there is no way for them to have an AO or AA baby. The baby can be Rhesus negative however, because the father may be heterozygous for the Rhesus factor.


If the father is 0 positive and the mother is o negative can the baby be a pos?

Yes, the baby could be positive. If the baby is positive the mother needs to get on immuno-suppressant drugs or she will have an immune reaction and her body will try to kill the "foreign object" aka the fetus. Best of luck.


What problems might occur if a mother is rhesus-negative and the father is rhesus-positive?

It is possible for there to be problems with a pregnancy. If mother's blood type is negative and the father's is positive, and the baby is positive, her blood type may begin to attack the child. Make sure she checks with her doctor regularly during a pregnancy.
