We are looking for the possible blood types of a baby.
Parental information:
- Mother type O pos -- can only have OO and Rh (++) or (+-)
- Genes to contribute: O, (+), (-)
- Father type O neg -- can only have OO and Rh (--)
- Genes to contribute: O, (-)
Baby recieves one gene from each parent:
- Baby is type OO (+-)
- Baby is type OO (--)
Generally speaking, because only one ABO gene can be contributed [O], the baby can only be Type O
HOWEVER: There is more to ABO blood typing that just the ABO gene.
There is also an inhibitory gene that will change any genotype into the phenotype O.
Therefore a person with genetically AB blood can be tested as having Type O.
- Baby is type A+ which can be genetically AA or AO
If one parent has the inhibitory gene affecting their AA, AO or AB type,
then the Type A baby is definitely possible.
___________________________________________________________**Yes. My son is 0- and my daughter in law is 0+ and they just had a A+ baby boy. It is very rare but the doctor said it can happen because every has a primary and secondary (recessive) blood gene. Since my d-i-law's father is A+ and her mother is 0+ and his parents are both 0+ but his mothers mother is A+ and her Father is 0+ there are many recessive A+ genes in their DNA blood type therefore they can have a A+ child. (Example mother is O+/A+ and father is 0-/A+ equals= A+/0 child.) 0 seems to be universal and can throw off a recessive gene. In our case; since it is rare; the baby and the mother's blood types caused him to have alot of jaundice (18) so he had to go back in hospital to be under the light for an additional 24 hours to bring it down. She was nursing and her milk had not come in to give him the fluids to fight off the excess billiruben count. Other than that; it will not be a problem for either of them.
Hope this helps, as it is hard to find this information on the internet. Most sights say no because they are stating the normal without considering the recessive secondary gene type that are rare. Ask a doctor .....it happens
What else can I help you with?
Can a child have a different blood type from the father?
My Mother was O pos. Dad was AB pos. Can I have a different blood type such as A pos? My siblings have AB pos.
If the DNA of the mother is A and the child is A pos what is the DNA of the father?
Given that the mother's DNA is A and the child is A positive, the father's DNA must also contain the A antigen. The father could be A positive, A negative, AB positive, or AB negative.
If a mother is A pos can her child be B neg?
Yes, this will depend on the father blood type, so for a child to be B-, the father could be either B or AB negative or positive.
What are the possible parental bloodtypes for a child with the blood-type A positive?
There are many possibilities, but two things are certain: at least one parent must be type A or AB, and at least one parent must be Rh + A child with blood type A+ can have the following combinations of parents: Mother A+, Father A+ Mother A+, Father A- Mother A-, Father A+ Mother A+, Father B+ Mother A+, Father B- Mother A-, Father B+ Mother A+, Father AB+ Mother A+, Father AB- Mother A-, Father AB+ Mother A+, Father O+ Mother A+, Father O- Mother A-, Father O+ Mother B+, Father A+ Mother B+, Father A- Mother B-, Father A+ Mother B+, Father AB+ Mother B+, Father AB- Mother B-, Father AB+ Mother AB+, Father A+ Mother AB+, Father A- Mother AB-, Father A+ Mother AB+, Father B+ Mother AB+, Father B- Mother AB-, Father B+ Mother AB+, Father AB+ Mother AB+, Father AB- Mother AB-, Father AB+ Mother AB+, Father O+ Mother AB+, Father O- Mother AB-, Father O+ Mother O+, Father A+ Mother O+, Father A- Mother O-, Father A+ Mother O+, Father AB+ Mother O+, Father AB- Mother O-, Father AB+
If mother is O positive child is A positive what must father be?
The father can be A-, A+, AB-, or AB+
If mother is B- and father B plus can child be AB?
If my mother is b- and my dad is b+ could there be a child ab- please
Can a mother has A positive blood type and a father has AB positive and the child has B positive?
Since both parents are Rh+, the child will also be Rh+.If the Mother is A0+ and Father is AB+, the child will be: AA+ AB+ AO+ or BO+ So yes this does produce a B+ child.If the Mother is AA+ and the Father is AB+, the child will be AB+ or AA+ neither of these is B+ so this doesn't produce a B+ child.
If mother and father is A blood group can child be B positive?
If the mother is A, and the father is A, then the child will only have A antigens and will thus be blood type A. If father or mother are AB, then the child can end up with AB, A, or B blood type. http://en.wikipedia.org/wiki/Blood_type
when father have ab mother 0 plus child have?
A or B
Can a A Negative Father and an AB Positive mother have an A Negative child?
The child will be A or B or AB, Rh+ or Rh- . So yes, the child can be A-.
What would be the blood group of child if father is A positive and mother is AB positive?
either "AB" or "A".
Can a type AB child have a father with type A blood?
Yes, if the Mother is type B or AB.
