Is it possible to have a blood group..?!
Question:
Is it possible to have a blood group..?
A, when all my immediate family are an O? I have been told that it can be a throw back to my great or grand parents, but what is the possibility?
Answers:
O is a recessive trait...so type O blood is always "OO"...type A blood can be AA or AO....so if your parents are both O , then NO you can not be their child, but if you are AO and you marry and AO person (both type As), then you can have either a type A child (AO or AA) or a type O child (OO).
