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.
Can parents who are B negative and O positive have a AB positive child?
No, it is not possible for parents with blood types B negative and O positive to have a child with AB positive blood type. The AB blood type requires an A allele from one parent and a B allele from the other, which is not possible in this case.
Can a child have A negative if one parent is A positive and the other is B positive?
no
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 a mother is A negative and father is AB positive what blood type could their child be?
I would need more information (like what blood types the child's grandparents are) to narrow it down. The child could be: - A negative - A positive - AB negative - AB positive - B negative - B positive
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.
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.
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 a person that has o positive blood and a person with a positive blood make a child that has a negative blood?
Yes, it is possible for a child to have a negative blood type if both parents are carriers of the Rh negative gene, even if one parent is O positive and the other is A positive. Blood type inheritance is determined by a combination of both parents' blood types and Rh factors.
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+-.
What blood type would a child have if one parent was b negative and the other b positive?
b posgative
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 parents who are B negative and O positive have a AB positive child?
No, it is not possible for parents with blood types B negative and O positive to have a child with AB positive blood type. The AB blood type requires an A allele from one parent and a B allele from the other, which is not possible in this case.
Can a child have A negative if one parent is A positive and the other is B positive?
no
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 a mother is A negative and father is AB positive what blood type could their child be?
I would need more information (like what blood types the child's grandparents are) to narrow it down. The child could be: - A negative - A positive - AB negative - AB positive - B negative - B positive
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.
