CAN A+ and A+ Make O+?

CAN A+ and A+ Make O+?

Yes, it is possible for parents to have type A blood and their child to have type O blood. The positive and negative of the blood is called the rH factor and is separate from the type of blood. There are two types of genes, dominant and recessive. Dominant genes are always expressed when they are present.

Can two a positives have a child?

So, is it possible for two people who are Rh-positive to produce a child that’s Rh-negative? The answer is yes — but only if neither parent passes along Rhesus D. The simple Punnett square here demonstrates how this is possible.

Can two Type A parents have a type O child?

Even though both parents still have blood type A, Dad can pass on either his A or his O gene version. Mom can also either pass on her A or her O. Because of this, you can see that there’s 1 in 4 or 25% chance for a child to have OO, or blood type O. One combination, OO, gives blood type O.

Can a baby be O + or O-?

Except in very unusual circumstances, they will have a child with Type O blood. THat could be O+ or O-. Without more genetic information, the chances are higher that the baby would be 0+ and lower that it would be 0-.

How many babies can you have with O blood type?

As you can see, dad has two O+ and two O- alleles. When we get rid of the extra one, we have this, easier to manage table: As you can see, only one out of the eight boxes is OO -/-. That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type.

Can a father with an AB blood group give his baby an O blood group?

Mother with AB blood type can either pass the A or B allele to the baby. Likewise, a father with O blood type can only pass O allele to the baby. If both parents belong to the blood group O, the child will also belong to the O blood group. Two A blood group parents can give their child either A or O blood group.

How are O + and O-parents alike?

Both parents are phenotypic O, in the father because he’s homozygous recessive in the ABO locus, the mother because she’s homozygous recessive in the Bombay locus and her A allele isn’t being expressed. They could have a child who was: I (A)i Rr Bb, who would be a type A+.
