Father could be AB, but an O mother is OO.
so,
AB X OO
AO and BO
are the only possible alleles from this cross
no
Yes, anyone can make a baby. It doesn't matter what blood type you have.
None. What you have to worry about is if the mother's blood type is (-) negative and the father's is (+)positive. When this happens, the baby inside the mother will be (+) and the mother will make antibodies to the baby's blood for the first pregnancy. This will not affect the firstborn, but will affect the second born. This is why they give Rh - moms a shot of Rhogam to keep the mothers antibodies from attacking the baby's bloodcells resulting in anemia.
No
yes, there is a chance to have a baby w/ A+
It is possible for there to be problems with a pregnancy. If mother's blood type is negative and the father's is positive, and the baby is positive, her blood type may begin to attack the child. Make sure she checks with her doctor regularly during a pregnancy.
Genetics do not make a baby, they determine whether the baby will be more like the father or mother. Genetics can help determine traits like a baby having hair or eye colour like the mother.
yea you will be the father and the baby will live with mother
Yes
If a mother who is blood type A and she donates her A allele to the baby, then it could definitely be type A.
The blood type should be O positive.
I honestly don't think that would matter. That would not make a difference, but if it was the mother smoking during the pregnancy it would certainly affect the baby. Not during conception though. The father only shares the sperm, not blood. There's no way it would affect the baby.
