14. Long Lost Son Blood Types & DNA Fingerprinting

15. Part 1: Blood Type Results Genotype(s) for Mr. Cash? Genotype(s) for Long Lost Son #1? Genotype(s) for Long Lost Son #2? IAIBIAIB ii I B I B or I B i

16. Can Long Lost Son #1 be Mr. Cash’s son? Can Long Lost Son #2 be Mr. Cash’s son? No. A person with type AB blood can never produce a child with type O blood. Yes. A person with AB blood can produce a child with type B blood.

17. Part 2. DNA Fingerprinting Which of Long Lost Son #2’s DNA match his mother? Which of Long Lost Son #2’s DNA match Mr. Cash? Which of Long Lost Son #2’s DNA do not match either? 3 & 4 1, 2 & 5 none

18. Is Long Lost Son #2 Mr. Cash’s biological son? Yes. Half of his DNA comes from his mother and half comes from his father (Mr. Cash)
