Can a O negative parent and an RH O negative parent make a positive baby?

No, if both parents are O negative (meaning they do not have the Rh antigen), they cannot have a Rh positive baby. RH positive blood type requires the presence of the Rh antigen when processing blood types.


Can negative and a positive blood type make a positive?

If one of the parents is A positive, the child could be A positive.


Can two parents with b positive make o positive?

Yes. The child will be either A positive or B positive or even AB positive. If the grandparents have a negative (A negative, B negative), there is a slight chance that the child will have a negative. A type O is out of the question. The fact that there are two positive parents means that there is no risk to the mother of Rh negative disorders.


Can parents both blood type b positive have a child with blood type ab positive?

Yes, it is possible for two parents with blood type B positive to have a child with blood type AB positive. This is because the child can inherit one B allele from each parent to make blood type AB.


Can two o positives make an o negative?

Yes this is true only if both parents are heterozygous positive. This means that the parents genotypes are +- for blood type. + blood type is dominant over - blood type, so this means that one can only have negative blood type if their parents are either heterozygous or homozygous recessive. A helpful tool to finding out the probability for this question would be to use a punnett square. If you used this method you would find out that two heterozygous positive blood type parents have a 25% chance of producing offspring with negative blood type.
