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.
**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
Yes, this is very possible, assuming that the mother's genotype is AO (she has genes for both A blood and O blood). Type O blood is recessive. If a person inherits the genes for both O type blood and A or B type blood, they will exhibit type A or type B blood, respectively. However, even two parents, both with a dominant type of blood, have a 25% chance of producing a child with type O blood (if both of them had the recessive gene for type O blood).
Yes. If mother was A/O RH pos (D d) and Father is A/O RH neg (d d), then they could have a O positive child. One only needs one big D to express the RH positive gene.
I believe that A is dominant over O blood type. I do know that the negative and positive could be either.
Yes, we all get our blood groups from our parents or even grandparents.
Yes, my husband and I are both type A+ blood and our daughter is O-.
Yes, an O negative mother can parent an A positive child. However, for this to occur the father must be either A positive or AB positive.
sometime yea
yes, if the mother is either A positive or AB positive.
The baby may be any of the following: * B positive * B negative * O positive * O negative
No. For a person to be "O" blood type, they have a phenotype of O, which can only come about if they have a genotype of OO. If both mother and father are O's then they have no B that they can donate to the baby.
CAN TWO POSITIVE BLOOD TYPES MAKE a negative blood type
Blood of animals contaion a factor known as Rh factor which was first discovered in Rehsus monkey, so name Rh and if it is present blood is called Rh+ of positive and if not then Rh-ve or negative simply.....
If the mother has type negative blood, and the father and child have type positive blood, the mother's blood may begin to attack the child's.
Yes.
Sure, if the mother is Rhesus (D) positive
rarely can be
yes, absolutely
Of course!
it can be rare only
Yes, as long as the mother's blood group is Rh positive, the baby can be Rh positive. Only one parent need be Rh positive for this to occur.
Yes, a father with A negative blood can have a child with A positive blood. If he does, the mother must have a positive Rh factor, and the mother's blood type may be any of the possibilities.
B positive or negative or, O positive or 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.
The first parent would be heterozygous for type A. The second parent would have to be heterozygous for type A, heterozygous for type B, or blood type O. The positive or negative is unable to be determined because positive is dominant so the first parent is positive then the baby will be positive with out a doubt so there is no way to find out the second parent's positive or negative.
