7. Remember… IA and IB are co-dominant i is recessive IA IA = Type A
IB IB = Type B
IA IB = Type AB
i is recessive
IA i = Type A
IB i = Type B
i i = Type O
A is anti-B, B is anti-A, AB has no antibodies (universal receiver), O has A and B anti-bodies (can only receive other O). O is universal donor; no one has antibodies against i.

13. Why We Care…
Today, we can use paternity tests to analyze a man’s DNA. If it matches the DNA of a child, this proves that they are father and son.
But it wasn’t always this way.
Back in the day, scientists used BLOOD TYPES and PUNNETT SQUARES to figure out…

14. WHO DAT BABY DADDY?

15. Scenario 1
Katie is heterozygous for Type A blood (IAi). Her baby is type O (ii). She is not sure if Richard, her husband, or Adam, her husband’s best friend, is the father…
Richard has type AB blood (IA IB )
Adam has type B blood (IBi)
