Can a A+ blood type male individual be the parent of an O+ male child?

Question

Can a A+ blood type male individual be the parent of an O+ male child?

Answer 1

Yes.  If the A+ male is heterozygous for blood type.  In a punit square the male would have to be A i or whatever you are using to represent blood type.

Answer 2

y not?

Answer 3

Yes. Basically the "O+" is due to the Rh factor being present on the man's red blood cells. The woman, however, does not have the "Rh +" on her red blood cells. Hence, the child genetically acquired the positive Rh factor from the male. The female would have two negative alleles. The male could have one "Rh +" and one "Rh -."

The genotype could be either Rh+/Rh+ or Rh+/Rh-.

Someone who is Rh- has a genotype of Rh-/Rh-.

Each biological parent donates one of their two Rh alleles to their child.

A mother who is Rh- can only pass an Rh- allele to her child.

A father who is Rh+ could pass either an Rh+ or Rh- allele to his child. This couple could have Rh+ children (Rh- from mother and Rh+ from father) or Rh- children (Rh- from mother and Rh- from father).

Basically, the woman has inherited both Rh- alleles from her biological parents. One from her Mother and one from her Father.

This is the most simple way for me to explain how the A,B, O blood groups, and more importantly, the Rh factor are relative to your question. Blood banking is very complex and difficult to comprehend.

I would like to state that the female, having O- blood is a universal donor which is wonderful. I must also state that a female with Rh- blood, should she become pregnant with a Rh+ fetus, poses grave health concerns to the fetus/baby. The incompatibility of the blood may have fatal consequences if not treated, immediately. One being the destruction of the red blood cells within the fetus. (hemolytic disease) This is just one of the complications that has a great probability of occurrence. A drug commonly used before birth when the fetus and mother's blood is incompatible is called Rhogam. It can drastically reduce the probability of serious complications.

Answer 4

absolutely yes.

Answer 5

Yes.

In the genetics behind blood groups, there are 2 dominant genes: the A and B, and 1 recessive: the O

You receive one copy of each gene from each parent.

If the copy contains an A or a B, it will override a copy that has the O.

However, if the parent is AO blood type (i.e. they are A+ as the O does not show itself because it's recessive), and marries somebody with AO, BO or OO as their genes, then there is the chance that the O from one parent will combine with the O from another parent resulting in an O positive child.

Answer 6

YES

Answer 7

yes if in thi case genotype of father is Ia,Ia or IaIo n +ve & mother genotype will be IaIa or IaIo n +ve or _ve

Answer 8

YES.

If a genotype of parents is AO and other parent is AO/BO/OO

a child can be OO i.e. blood group O
