Yes it is, because A type blood is either AO, or AA, since just like hair and eye color, you have 2 of each. If both parents have AO, and they each passed the O on, then the child would have O blood, which is really OO. I hope that helps.

Have you ever seen a Punnet's Square?
Type A is dominant, Type O is recessive. So both parents have two genes....one is A and the other is O. It would have to be that both parents have an A and an O gene. The baby has a 25% chance of having two A genes, 50% chance of having A O, and 25% chance of having two O genes. If the child has any A genes at all, the child will have type A. If it is the two O genes, the child will have type O.

Yes, it is possible. Since you are both A+, your children will either be A+ (75%) or O+ (25%). If you were to have a lot more kids, that would be the spread. Each child has a 75% chance of having A+ blood type. If you even get a baby that is B+ or AB+ one of you isn't the parent.

A+ can either be carrying AA ++, AA+-, AO++, AO+-. As the A blood type and the positive blood type are dominant.
That means that two parents of A+ can have children that are:
A+, A-, O+, or O-

yes it is possible. both parents have to be AO+ so the child is OO+. The second type just isn't referred to, so most people don't know about it. Like the one above me said, that is how hair color, eye color, etc. won't show up in the parent, but is obvious in the child. It all depends on the parents.

definitely. when a person has blood group A its actually AO (and B is actually BO)
So if the baby gets the two 'O' genes from both parents, their blood type will be O

yes because of recessive genes in genetics
I mean, another example is that my sister and brother in law both have black hair, but they have a little boy with blonde hair! Strange huh? funny how things happen

Well obviously so since it happened. Genes are a tricky thing, anything can happen. Maybe this person was just meant to donate blood or something. Thats kinda cool, having O

Anything's possible with genetics.
