You find yourself in a scenario similar to the movie “Mamma Mia.”   One of your old friends has just had fraternal twins – a boy and a girl.  She wants to receive child support from her babies’ father but she doesn’t know who he is.  Luckily, you, her trusted friend, work in a molecular biology lab. She has come to you for help, so you perform DNA fingerprinting on samples of blood from the mother (M), the two babies (B1,B2), and three men (a,b,c) that the woman had one-night stands with nine months ago.  Who should she ask for money? Choose a, b, c or a combination of two, and explain your answer.
