Blood Types Problem Set

Problem 6: Do we all have the same biological father?

We were surfing the net for information on how to confirm blood types inherited from our parents. Your home page offered a lot of good, basic information, but since we are non-bio-science types, our understanding is dated back to high school. Could you offer a reference that would be helpful to figure out blood typing. We understand that a ABO matrix is part of it, and we expect it to be technically over our heads - but we're willing to try. Our basic question is: What is the blood type consistency of two parents who are O+ who have 8 children? 2 of 8 are reported to be O+ and O-. Does that seem to be likely?? --John
