Hi all, I am curious if anyone knows how we get our blood type. If I am type O and my brother is type A then what perhaps was my mom and dad? (They are both deceased now) I think one is recessive and one is dominant. I am trying to find out what type my kids are. If my husband is type A and I ma type O can they be both type O possibly? Due to so many problems with food sensitivities I am exploring the Eat Right for Your blood type program/diet. I apprciate it if anyone knows about this. Blessings! Diane
