No, not possible. A baby with both O+ parents will 100% certainly be O+. A baby with an O+ and an AB can result in a baby with A+ blood though... Confusing I know! Kind of complicated!

That's definitely not possible.
Type O blood is recessive. If someone has type O, then they are homozygous for that trait. Always. And if both people are type O, then there is just simply no other blood type encoded in themselves to pass on to their children.
Some people with type A are homozygous, which means that they can only pass on type A. Others are heterozygous, and can pass on either A or O. The same is true for type B. And type AB is what happens when blood has a mix of A and B antigens. (Sorry if this is getting too technical!)
OK, here's an example. When I got pregnant, I already knew that my blood type was O. (My dad is O, and my mom is heterozygous for B.) I asked the father what his blood type was, and he said O. So I immediately knew that the baby would be O. When she was born, sure enough she turned out to be O. When we got pregnant again, I had already been told that his blood type was O, and based on that information knew that all babies would be type O, so I didn't ask again. Much to my surprise, after the delivery the doctor said he was type A! I asked the father nonchalantly what his blood type was and this time he acted confused and said "I don't know, maybe B?" So it turned out that he never really knew. But based on the blood types of our two children, I figured out that he must be heterozygous A (carrier for O). I asked his mom if he was type A, and she said yes.
So there you go, a real life blood typing example LOL.
Out of curiosity, are you asking this about your own parents' blood types in relation to yours? When I was first learning blood typing in school, I knew mine and my dad's but got my mom's wrong. I listed her as having AB. My teacher said, "These can't be your parents!" My heart skipped a beat. Later I realized my mistake lol.

I did a quick internet check, and it doesn't seem possible to have a A+ child when both parents are O+. However, mutations happen in biology, and it can turn out that the child is the biological child of both parties. This is why blood types can not be used to determine paternity. If there is a question about the baby's paternity, a dna test would need to be done.
Dna test can be purchased on line for under $300. If a man has doubts about paternity but didn't want to ruffle any feathers, that would be the way to go.

I didn't think so. I thought only A and AB blood could make an A blood baby. As for the previous answer. O blood does have Rh. I am O+, as confirmed by my doctor today from a blood draw.

If both parents are O+, the baby can either be O+ or O-. If both parents are O - the baby can only be O-.

I know that two parents who are A positive CAN have an O positve child.
Check the Encyclopedia Britannica under blood types.

No, it is not possible. The A blood type has only the A antigen, while the O blood type has neither the A nor the B antigen.

yeah, there IS a such thing as O+ blood. I am not sure but I am pretty sure that it is possible. My grandmother on my mothers side had nine children all had AB blood type except two of them that are O+ and both of my grandparents are O+, that is why I think that but idk if that is a fact or not.

i'm noticeably confident that their expert standards does no longer enable them to assert something. finally, the mother and the new child are the sufferers. the daddy isn't a affected person and there is not any reason they might desire to tell the daddy. there is probably no reason they might desire to tell the mother the two in the event that they think of the "father" isn't the daddy (in spite of everything, she might desire to have a existence like theory besides). additionally, as you're saying, the sperm might have been donated. it relatively is not the physician's place to be making comments while (s)he perhaps would not be attentive to the excellent situations. If no longer something, i could think of the physician in the occasion you provided is being downright rude. in my opinion, while my daughter grew to become into born (in the united kingdom), i'm noticeably confident the medical doctors did no longer be attentive to my blood type. it may be exciting to hearken to from a doctor in this one although. i've got study the place a minimum of 10% of little ones in the united kingdom have fathers different than the guy that thinks he's the daddy (examine accomplished utilising bloodtyping - i think of it grew to become into referenced in "technological expertise of Discworld" or something). i could guess that lots of the fathers in touch could prefer to be blissfully ignorant and proceed loving their new child for who they think of they're.
