Paternity Test
A wealthy man named Sam has recently died. He was married to a woman named Amy. They had two children, Bill and Donald. When Sam died, he left $50 000 to each child.

A woman named Sarah called the family, and told them Sam was her father too. They decided to do a paternity test to determine if Sam is Sarah’s father.

They compared the blood of the two children, as well as the blood of Sam, Amy, and Sarah. The results of the gel electrophoresis are below.
