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.
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. The Mother is IAIB and the father is ii. So, in gamete formation, the mother will produce IA and IB, while the father only produces i. When the gametes fuse, there will be two possible genotypes (and phenotypes) for the baby: IAi (A blood type) or IBi (B blood type). The Rh factor (+ or - ) has no relevance in this question, really. The REAL father can be either: IAIB, IAi, or IBi. The child MUST get an IA or IB allele from the father.
ab+ a+ b+
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.
there is no problem with that, your Rh+ comes from your mother :) ur father genotype is Rh-Rh- your mother should be Rh+Rh+ or Rh+Rh- so you took one Rh- from your father and one Rh+ from your mother the result will be Rh+Rh- and because the +ve propriety is more dominant your blood type will be +ve even if you have the mix of Rh+Rh-
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
yes can
Yes
Yes - and the baby will have a blood type of O.
it is possible but chances are rare.
