Why can the blood group of a mother and her baby not be the same after birth?

It is entirely possible for a parent to have a child with a different blood type.
What you may be asking is about the danger of Hemolytic disease associated with giving birth to a child with a different blood type. In rare circumstances, the fetal blood can cross the placenta and enter the mother's blood. If the blood type is incompatible, the mother will develop antibodies against the fetal blood. This, by itself is not a problem. However, if the woman has a second child with an incompatible blood type, the antibodies can cross the placenta into the fetus, resulting in a life-threatening condition for the fetus.
This typically happens with mothers with Rh-negative blood, where the fetus is Rh-positive, due to the father's genes. There are successful treatments and preventative measures for this condition.

Can father is A blood group and mother is B blood group and baby is male or female?
It depends. If the mother is heterozygous rh+ rh- for the rh blood type, then the baby could inherit an rh- allele from both parents, and then it would be rh negative.

How does erythroblastosis fetalis develop?
It happens when the father is of a positive blood group (having Rhesus (Rh) factor) and mother of a negative blood group (devoid of Rh factor), the fetes' blood group will be of the positive type, i.e., having Rh factor as having Rh factor is a dominant trait and can mask the negative blood group. So, this creates problems for the kid as well as mother during pregnancy. Usually, the first pregnancy will not have much complications. But, the second pregnancy onwards, the antibodies present in the mother from the first pregnancy will be present and is harmful for the fetes.

Can a mother with a negative blood and father with o positive blood have b positive blood group baby?
No. For a person to be "O" blood type, they have a phenotype of O, which can only come about if they have a genotype of OO. If both mother and father are O's then they have no B that they can donate to the baby.

B+
What happens when husband has Ab negative blood group and wife has A plus blood group?
Nothing happens, also nothing happens to their babies. Because the mother is Rhesus positive she won't make antibody's against the baby's blood. The only danger is when a Rh negative mother gives birth to a Rh positive child. RV
3 mo old baby has a low blood count mother is negative blood and father positive can this be the cause of the low blood count?
This can be a cause if the baby had a low blood count from birth or very shortly after, especially if this is not the first pregnancy. Hemolytic disease of the newborn can be caused by the mother's antibodies attacking the baby's red blood cells if the baby if Rh positive and the mother is Rh negative. The antibodies get into the baby before birth, however, so if the baby developed a low blood count at 3 months it would not be because of the negative/positive blood type.
