A or O

In blood types, there are three alleles: A, B, o.
A and B are dominant and o is recessive.
Two alleles make up the blood type gene.
Thus, there are 6 different combinations.
AA or Ao = Blood Type A
BB or Bo = Blood Type B
AB = Blood Type AB
oo = Blood Type O.
If the father is O, his gene must be oo and he will pass an o allele to the baby's blood type. If you are A, you could be either AA or Ao. If you are AA, then you will pass an A allele to the baby's blood type and the baby will be Ao = Blood Type A. If you are Ao, then you could pass either an A allele or an o allele to the baby's blood type and the baby could be Ao = Blood Type A or oo = Blood Type O.
Thus, your baby will either have Blood Type A (likely) or Blood Type O (possible).
Unfortunately, I do not know anything about the genetic traits of the rhesus factor (+/- factor of blood). However, I do know that a mother with a negative factor must be extremely careful. If she carries a child with a positive factor once, the mother's body will be exposed to the positive factor and will develop antibodies against it. This does not usually affect the first child. If, however, the mother should conceive a positive factor child a second time, the antibodies in the mother's system could attack and possibly kill the child. However, this can be remedied by the administration of antibody-blocking antigens to the mother which any good OBGYN should notice and take care of. It doesn't hurt to inform your doctor of this situation. If the mother carries a negative factor child, there is no chance for harm to the child whether the mother has developed antibodies or not because the child does not have the positive factor to which the antibodies would attack.
However, as I said, I am unaware of the genetic traits of the rhesus factor, so I cannot help you predict the rhesus factor of your child. Sorry.

Your baby either will be A or O but the rh factor (+/-) is not set in stone based on your question. That's because the O positive rh factor could be comprised of either combinations, both being typed as O positive. The first is the total rh positive which is O +/+. That's because both of the person's parents were positive. Or you can still be an O positive if you are O +/- (also O positive). That means that the persons parents had two different rh factors. With an O+ having two different possibilities to get selected for a baby when the miracle of birth happens, an O+ dad with parents of different rh factors puts a huge question mark in the air.
Since the positive rh factor is dominant and there are two genes
to select, if the baby draws the negative if the O+ candidate's PARENTS have different rh types, then you will have an rh factor negative baby. If your baby draws the positive gene from this candidate, you will have a O+ baby.
You would have to know for sure your O+ candidate is for sure +/+ to be able to tell by blood type analysis. The recessive gene guarantees that the O neg candidate must be -/-.
There is probably a need for a paternity test though since they don't blood type anymore, they do DNA analysis probability. I am sure now you see why
PS I am A- too and my husband it O+. We have 2 kids, the first is O+ and the second is A+... but my kids could have been O- or A- if my husband for sure was O+/- = O positive.
Sorry the answer is you don't have enough information and you are going to have to do a DNA test. Problem is even if you ask he's not going to know what his parents blood type is.... even my own MOM swears I'm an O+! That blood will make me sick or kill me, thank GOD she didn't get me a transfusion.

O variety blood is recessive, AB blood ability the guy has the dominant A and dominant B gene, grossing oo and any possibility will on no account bring about AB because of the fact one o could take transport of and the offspring could have an A and a B. so no, it could not happen.

Seeing as you being an A- and the father being either O+ or O- it could be an few possibilities such as A-, A+,O- and O+. You know this by doing a punnet square and using the basic genotypes.

A- or O- (and you won't know who the father is).
If the baby is A+ or O+, the other guy's the father.

it is either A or O if you do a test cross
parental genotype : means u n ur hubby
AA X OO
offspring = AO
since A shows a complete dominance, therefore = A
If genotype is : AO X OO
offspring is : AO or OO

your unborn child's blood type will either be A-, or OA. as o is the universal receiver
