Yes. I am O positive and my husband is A positive and our son is O negative. This is because my husband and I are heterozygous for rH factor, and we each passed the recessive allele to our child.

∙ 12y agoSorry, but the answer is no. Blood type "O" occurs only if type "A" and/or "B" are NOT present. If both parents are type "O", then all their children will be type "O". Depending on each parents genes for the Rh factor the child could be Rh+ or Rh-However, sometimes blood typing "misses the mark" in other words, maybe they did it wrong and it needs to be done again.My wife and I test as "A+". we have one son who is "O-".This can happen if both my wife and I have a gene for type "A" another gene that is not "A" or "B" (or as is commonly used, type "O"), another that is Rh+ and finally a gene that is not Rh+ (or is labeled Rh-). So we have 16 possible combinations with the four genes involved, one of which is "O-".

No. Two rhesus-negative parents cannot have a rhesus-positive child.
