What blood type do I have?!
Question: What blood type do I have?
My mom has A- and my dad has B+, but I have no idea what mine is. Is there a way to determine ones blood type with this information? I also know my grandmother (on my mother's side) has O- if that might help...
Answers:
No, there is no way. You can have a completely different blood type to both of your parents.
You will need to get a test done.
