No, it would be impossible for two Type O blood parents [regardless of their Rh factor] to have a Type AB baby. I'll try to explain why. Blood type is determined at the moment of conception by a combination of two genes: one gene that comes from the biologic mother and another gene that comes from the biologic father. The gene for blood type O is recessive, and the genes for types A and B are dominant. A person with type O blood has two genes for type O blood [recessive], and that's the gene he/she will pass on to each and every one of his/her offspring. A couple in which BOTH partners have type O blood will necessarily produce type O blood offspring exclusively. If a child with other blood type {type A or type B} is born to such a couple, it means that the man isn't this child's biological father, because neither he nor his wife has another kind of gene but type O to pass on to their offspring. A person with type AB blood has received one type A gene AND one type B gene {both of them dominant}, one from each of his/her parents. In this case, neither of this person's parents can possibly be type O blood; they could be only one of the following combinations: one AB + one A; one AB + one B; both AB; one A + one B.
In my particular case, I'm type AB blood; my husband is type O; our daughter is type A, since she received a type A gene {dominant} from me + a type O gene {recessive} from my husband. If we were to have more children as a couple, ALL of them would be type A -OR- type B; NONE would be type O; NONE would be type AB [unless I cheat on him with either a type A, type B or type AB guy].

No, the RH factor (positive/negative) has nothing to do with blood type.
O is a recessive gene and A & B are codominate. To have an AB child the parents would have to be one of the following combinations: AB+AO, AB+BO, AB+AB, AB+AA, AB+BB, AA+BB, AA+BO, AO+BB, AO+BO.
If the parents are AA+BB then the child will have the AB blood type. With AA+BO or AO+BB there is a 50/50 chance of the child having an AB blood type. With all of the other combinations there is only a 25% chance.

A person with a O-type blood group doesn't express genes necessary to make the A and B antigens that are what makes a blood type A and B. Therefore, if both parents are type O, then logically speaking their child will not inherit any genes that make the A and B antigens. So the child will almost certainly be an O-type.

No, they can't. O is a recessive trait. Two O type parents can only make a type O baby. The parents were either A, B, or AB to begin with. The Rh factor (-, +) is another story altogether.

Can a Father with A - Blood Type have a daughter with O + Blood Type?

Giving birth to a new life is indeed a blessing which almost every woman would wish to have. How to get pregnant naturally https://tr.im/preventinfertility
Enjoying the feeling of motherhood and raising a family would surely be a couple’s dream. Some get it naturally, while for some others things don’t seem to work as they desire. These reasons which stop a women from conceiving can be due to either physical reasons or truly physiological.

No, regardless of positive or negative, two O parents can only make an O baby, nothing else. Whether it is positive or negative is arbitrary.

No, you can only make an o type baby. either negative or positive.

No, I don't think so. From what I have been told, the baby usually ends up with the father's blood type, and doesn't sound like the father has type o blood
