Can an AB father and an A mother have an O baby?
June 1, 2011:
My mom was A blood type and I am AB. I believe my dad was O although he also is Bombay blood group. I was told this means my dad was not my dad, is that true?

Where does Rh negative blood truly originate from as I have seen several sites speaking of reptilian blood and blood of the gods? What is that all about and is there any truth to what is said?

If both the father and mother of a child have the blood type B, what possible blood types could the baby have? And, while we're at it, what are all the possible blood types for any combination of parents?

I have the A Negative (A-) blood type. My mother has the A Positive (A+) blood type, and my father has the O Positive (O+) blood type. So, how can I have the A- blood type if both of my parents are + blood type? Could I have gotten my blood type from one of my grandparents?

I am 15 weeks pregnant and I recently had a series of bloodwork done. I found out that I was AB+. My father is definitely O- and my mother is unsure of her type. I have seen online many sites that say this is not possible, that my father cannot have O-. Is this correct?

Is it possible for 2 Rh negative parents to produce a Rh positive child? I am pregnant with my second child. My blood type is O-. My husband and daughter both have A-. At my last OB appointment I was told that at my next visit I would have an antibody screen and most likely need a Rhogam shot. I know this is administered as a precaution in case the baby is Rh+. However, I understood this to be impossible since both my husband and I are Rh-. When I questioned the nurse, I was quite surprised when she told me that it IS possible to have an Rh+ child because of recessive Rh+ genes. Is this true? All the information I have found so far leads me to believe this is impossible. (And yes, I am 100% certain beyond a shadow of a doubt that my husband is the father of my child).

Whose blood do we carry, our moms or dads? Or it doesn't matter because it could be from either one?

I am a redhead and I have Rh negative blood. Is there any genetic correlation between the two? Also, what is the difference between Rh negative and Rh positive blood types? Thanks
