Absolutely. There are two different factors here, the A/B/O stuff, and the positive/negative stuff. We'll take them one at a time.

A, B, and O are the three different genes. Of them, both A and B are equally dominant, and O is recessive. That means that anyone with one A and one O is type A, anyone with one B and one O is type B.

The only way to be type O is to have both O and O. To sum up: Genes and Blood Types Gene 1 Gene 2 Resulting Blood Type A O A A A A A B AB B O B B B B O O O So. If Mommy is type AB, that means she has one A and one B.

If Daddy is type O, he has two O's. Each child inherits one of Mom's genes, and one of Dad's. Dad will obviously give junior an O, since that's all he has.

Mom will give junior either an A or a B. So junior will get either A-O or B-O, resulting in blood type A or blood type B. So it is 50% likely that a child born to AB and O parents will be type A.

Now, the second part, the positive and negative. In this case, positive is dominant, and negative is recessive. Again, every person has two.So someone with ++ is positive.

Someone with +- is also positive, and someone with -- is negative. All we know so far is that Mom is positive and Dad is positive. We don't at all know if that means that Mom and Dad are ++ or +- each.

We do know that each child will receive one gene from each parent. Therefore, here's the possible combinations: Positive & Negative inheritance Mom Dad Junior ++ ++ ++ (positive) ++ +- ++ (positive) or +- (positive) +- ++ ++ (positive) or -+ (positve) +- +- ++ (positive) or +- (positive) or -+ (positive) or -- (negative) As you can see, if both Mom and Dad are positive because both have +-, then there is a one-in-four chance that Junior will be negative, having happened to inherit the negative gene from both parents.In summary, yes, it is entirely possible that an AB+ and a O+ set of parents could have one (or more) A- children. Sources: genetics .

Nope, one parent needs to be negative. O is a recessive trait, A and B are codominant. An O parent has two O genes, with an AB obviously having one each of A and B.

Their kids have a 50% chance of being either A or B, not both, and not O. There is no difference between someone that is Ao and someone that is AA. (Other than having the possibility of having O kids.) But without the RH positive gene, you won’t have RH+ kids.

Did someone just find out their parents aren’t who they think they are? :) .

2 Funny MrItty, I think I demonstrated an understanding of dominant and recessive genes in my answer. I guess you're just being a jerk. I'm not sure why I thought negative was the dominant gene, however.

3 Oh my god. Are you serious? Do you understand what "Dominant" means?

Positive is the dominant gene. I never once said that negative is dominant. Read my answer again.

You have demonstrated NO correct knowledge of dominance vs recessiveness. If someone is positive, they either have two positives or one positive and one negative. That's what positive being dominant means.

Since it's possible for both parents to have one positive and one negative, both parents could pass on their negative gene, resulting in the offspring having negative and negative, resulting in the recessive negative trait being displayed. I am not being a jerk. It just pisses me off that someone who does not know what they're talking about would have the gall to tell someone they a certain parental combination is impossible.

That's the kind of thing that could destroy a family, if the asker is unfortunate enough to believe your VERY WRONG answer.

Mr_M_told_U_so replied to post #3: 4 MrItty is RIGHT. The two CAN have "A negative" babies. This is not an opinion question.

These are the scientific facts.

" "can two o positive parents have an o negatve baby?" "My blood group is A positive and my fiance is AB positive. Are we compatible? " "if my blood type is ab- can my child have ab+" "Where can I go to get my blood type tested.

My blood group is A positive and my fiance is AB positive. Are we compatible?

If my blood type is ab- can my child have ab.

Where can I go to get my blood type tested. Because My dad is ab negative and my mom is o positive and i'd like to know.

Blood type baby. I seem to be not understanding o.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
