Can O+ Parents Have O- Baby

Likewise a father with O blood type can only pass O allele to the baby. If there arent enough red blood cells the baby might not receive enough oxygen.

For example both your parents could be type A but you could still end up with type O.

Can o+ parents have o- baby. Each of their kids will also have a 3 in 8 chance of having A a 3 in 8 chance of being O and a 1 in 8 chance for being A-. O negative donors who are CMV negative are known as Heroes for Babies at the Red Cross because it is the safest blood for transfusions for immune deficient newborns. More specifically consider the following.

For example two O blood type parents can produce a child with only O blood type. She is A blood type but like the father also carries an O version of the ABO gene. Red blood cells carry oxygen to all parts of the body.

The babys genotype will be O-O-. The phenotypes of the parents would be O in both cases. If both parents belong to the blood group O the child will also belong to the O blood group.

Two O parents cannot have a baby that is anything but O. In fact every one of their children would have a 1 in 4 chance for being O. Two A parents could have an O baby.

Each of their kids will also have a 3 in 8 chance of having A a 3 in 8 chance of being O and a 1 in 8 chance for being A-. That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type. However after that there are no hard and fast rules.

An A parent and an O parent can definitely have an O- child. If the parents pass on an Rh gene the baby will be O. Rh incompatibility usually isnt a problem if its the mothers first pregnancy.

That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type. O negative blood type can only receive O negative blood. The mother A B.

The genotype of the children would be AO BO. Only 7 of the population have O negative blood. This will prevent expression of the A antigen masking the A phenotype resulting.

If a fathers Rh factor genes are and the mothers are the baby will have one from the father and one gene from the mother. Two parents with B blood type can produce a child with either B or O blood type. This would cause a problem with the second pregnancy with a O child when the antibodies would then attack the blood of the child and harm it.

And this is just the most common way an AB parent can have an O. That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type. Two A blood group parents can give their child either A or O blood group.

A baby receives one gene from the father and one from the mother. Thats because the babys blood does not normally enter the mothers circulatory system during the pregnancy. As you can see in the image to the right these two parents can have an O child.

After birth the baby can appear lethargic have low muscle tone and yellowing of skin and eyes jaundice. So the baby could possibly be O with a genotype of OO or OO- or it. If a mother is O positive for example and the baby has blood type A or B the mother may produce antibodies that destroy some of the newborns red blood cells.

Probably what you are worried about is in the opposite case where the husband would be O and the wife O-. During the birth though the mothers and babys blood can mix. This results in an increased amount of bilirubin and can cause more severe jaundice requiring treatment.

The requirement for this to be true is that the carries or the A allele is also homozygous for the recessive gene for the H allele. On the other hand if the mothers blood type is A and the fathers is B the child could be ANY of the four blood types A B AB or O so its ability to predict paternity is minimal in this case. One parent with A and another with B can produce a child with A B AB or O blood types.

Fetal hemolytic anemia can lead to serious illness and potentially death. It is possible that each parent hides an Rh - gene If they do and they pass that gene to their baby the baby will be O-. Mother with AB blood type can either pass the A or B allele to the baby.

The genotype of the father or possible genes he could pass on would be O O. Barry Starr Stanford University. If both your parents were type O then you will be O.

If she were carrying a baby that was O a 50 she would make antibodies to the O blood. Each of their kids will also have a 3 in 8 chance of having A a 3 in 8 chance of being O and a 1 in 8 chance for being A-. Two parents with A blood type can produce a child with either A or O blood types.
