Nope. Generally there may be problems only if mother is negative and the father is positive.
The antibodies to A/B blood types are too large to pass through the placenta and so cannot hurt the baby.
Yes. That pair have no blood type incompatibilities.
Sure.
No.Two Rh-'s always results in an Rh-.
Usually not the first pregnancy, but if the baby is rh positive, during birth some of the baby's blood may cross into the mother's bloodstream and then she will be sensitized and will produce anti-rh antibodies, which could harm the second baby if it is rh positive. There is an injection that is given to rh negative mothers during pregnancy to prevent this reaction.
Just because the babys blood and the fathers blood is different, it doesnt mean that there is a possibility that he ain't the father. For example, my fathers blood is different from my sisters and including but he still my father. I hope that answered your question. You are A dominant, but you have the O+ recessive gene. To rephrase what the others have said- if the mother is A plus, she would be AA or AO bloodtype. The father is something with an O as well, if the baby has an O. Father could be BO< AO< OO etc. (or he could have negative blood, and still have a positive blood child from this union)
No
yes
yes, there is a chance to have a baby w/ A+
yes
If the mother and father are both type O, the baby cannot be type AB.
then the baby will be O plus, or AB plus , I think .
yes, it is possible.
yes can
Yes
Yes
Yes - and the baby will have a blood type of O.
it is possible but chances are rare.
