If both parents are A positive can a child be B positive or negative?

Maybe. A child will have either the mother's blood type or the father's blood type. If the father is B+ and the mother is A- then it is possible that the children have the same father. So it all depends on both parent's blood type.Source: I am a 2nd year nursing student, and we had a long discussion about this subject last semester.


How can a child's blood type be A positive if mom is O positive and dad is AB negative?

If one parent is O positive and the other is AB negative, the child could inherit the A allele from the O positive parent and the Rh factor from the AB negative parent, resulting in the child being A positive. Each parent passes on one allele for blood type and one allele for Rh factor, so different combinations are possible.


What blood type would a baby have if mom and dad were a positive?

A/O, B/O, or O/O any combination. Each parent contributes one gene, A and B are dominant, so any combination that could result in O/O would result in a child with O blood. The Rh factor is similar. Rh positive is dominant, so the child would have to inherit 2 negative genes to be Rh negative. Each parent contributes 1 of the 2 he/she carries. Almost any blood type can result in a child with Rh + blood. +/+ or +/-. The child would have to inherit the - gene from BOTH parents (they would both have to be +/- or -/-) in order to be Rh negative. If both parents are Rh-, the child would be Rh-, otherwise it is hard to predict. Even if both parents are Rh+, it is possible for the child to be negative if both carry the recessive negative gene.


Can you have O Negative blood if your mother has O Positive and your dad has A Positive?

Yes, if the father's genotype is AO, and both of them have +- genotype. However, this would be very rare.


What is the blood group of child of an o positive father and ab negative mother likely to be?

50% chance of A. 50% chance of B. either positive or negative(shruggs). If the child is AB the mother screwed around on the 'dad' If the child is O you did the test wrong, because their is no way the woman can be wrong about whether or not the baby came out of her

Can an O positive mom and an A negative dad have an a positive child?

No, they cannot.


Can an O negative mom and an A positive dad have an O positive child?

No, they cannot.


Can A positive parents have A negative child?

Yes. A negative Rh factor is recessive. Everyone has 2 copies of this gene (one from mom, one from dad.) Since positive is dominant and negative is recessive, if you have one of each (heterozygous), you will have a positive blood Rh, but sitll carry the gene for negative Rh. If this is the case for both parents, then the child has a 25% chance of being Rh negative.


CAN A mother be a positive dad o negative and have a a positive baby?

Negative is recessive...you can have a negative also.

Can a blood type b negative man father a blood type a positive child?

Yes, it is possible for a blood type B negative man to father a blood type A positive child. The ABO blood type system is inherited from both parents, with each parent passing on one of their two ABO genes to their child. This means that the child could inherit an A gene from the mother and a B gene from the father, resulting in a blood type of A positive.

Yes, if the father's genotype is AO, and both of them have +- genotype. However, this would be very rare.
