Can O and B parents have a child?
A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter….How are ABO alleles inherited by our children?
| Inherited | Blood type of child |
|---|---|
| O from the mother B from the father | B |
Is O and B compatible for pregnancy?
Although your blood and your baby’s blood typically do not mix during pregnancy, a minimal amount of your baby’s blood and your blood could come in contact with each other during delivery. If there’s an Rh incompatibility and this happens, your body might produce Rh antibodies against Rh factor.
What blood types cant have a baby?
A-B-0 and Rh incompatibility happens when a mother’s blood type conflicts with that of her newborn child….A-B-O incompatibility occurs when:
- the mother is type O and the baby is B, A, or AB.
- the mother is type A and their baby is B or AB.
- the mother is type B and their baby is A or AB.
Can two a and O blood types have a baby?
Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type. If one parent has A and another has O, they can either produce a child with A or O blood types.
Why can’t I have an O child if I have AB?
The reason why an AB parent usually does not have an O child has to do with how blood type normally works genetically. Remember, we have two copies of each of our genes – one from mom and one from dad. This is true of the blood type (or ABO) gene as well. The ABO gene comes in three varieties: A, B, and O.
Is it possible to have an O blood type with Abo?
The one exception is in certain Asian groups. Some of these folks have a rare version of the ABO blood type gene called cis-AB. People with this gene version have an AB blood type but can easily have an O child.
What is the blood type of a child with B mother?
If the Mother’s blood type is B, and the father’s blood type is O, then their child must be either B or O. For instance, if both mother and alleged father have type A blood, then the child can only have A or O blood.
