If the fetus is O positive, there will be no problem. If the fetus is O negative and is the first O negative baby, nothing will happen to it, but the subsequent O negative fetuses will be miscarried unless the mother takes some special injections during this pregnancy.

Can O positive and an A positive make O negative baby?
A person with A positive blood may be a carrier for O negative blood. If the other parent is also a carrier of those traits, the baby could be O negative.
Can a father o positive and a mother o negative have a son o negative?
Yes. For the child to be O negative, he must have inherited an O from each of his parents and an Rh negative from each parent. This is possible with an O positive parent and an A positive parent. Blood type O can only be in the form OO (an O from each parent). Blood type A can be either AA (an A from each parent) or AO (an A from one parent and an O from the other) since A is dominant over O. So, if one parent is the AO variety of A, an O can be given. Thus, two Os can be given if one parent is blood type O and the other is blood type A, causing blood type O in the child. Rh positive can be either two Rh positives (a positive from each parent) or one Rh positive and one Rh negative since Rh positive is dominant over RH negative. Rh negative can only be two Rh negatives. If each Rh positive parent is the combination of one Rh positive and one Rh negative, they can each give an Rh negative to the child.
Can one parent have b positive blood and the other parent have a positive blood have an ab negative child together?
Yes, if the first parents' genotype is either BB+- or BO+-, and the second either AA+- or AO+-.
How can a child's blood type be A positive if mom is O positive and dad is AB negative?
because the dad blood was stronger and one positive and one negative make a positive
What blood type would a child have if one parent was b negative and the other b positive?
b posgative
Can a child have A negative if one parent is A positive and the other is B positive?
no
Will parents with a positive blood type have children with a positive blood type?
There is 50% that children will be of negative blood type if parents are heterozygous positive. 25% if one parent is homozygous and other heterozygous. 0% if both homozygous.
Can a o positive father have an AB negative child?
No. In order for someone to have AB blood, they must inherit the A from one parent and the B from the other. Therefore a parent with O blood could only have A, B or O children (depending on the blood type of the other parent).
If one parent has A positive blood and the other had A positive blood what type will the baby have?
The blood type would be A positive.
Can b positive parent have child with a positive blood?
A B+ parent can have a child with A+ blood. The other parent must be type A or type AB for this to occur.
A child is born with type AB blood what blood must the parents have?
The most likely blood type for the child is A positive - but A negative, O positive and O negative are also possible depending on the genotypes of the parents. If both parents are heterozygous AO, then the child could have either A or O type blood. If either parent is homozygous, AA, then the child must have blood type A. If the parent with positive blood is heterozygous, Dd (+-), then the child could have either positive or negative type blood. If they are homozygous, DD (++), then the child must have positive type blood.
Can parents with both negative blood parent a positive child?
absolutely. as long as one of the parents is positive, the child can be positive. and if one parent is A the other B, the child can be A, B, AB or O depending on the parents' other alleles. so the child can definitely be A or B positive, but also A negative, B negative, AB negative, AB positive, O positive or O negative.
