The parents of a new baby believe they brought the wrong child home from the hospital. Gel electrophoresis was performed using DNA samples from the parents and the child. A section of the gel electrophoresis results is shown below. Which conclusion is valid based on the gel electrophoresis results?
They have the correct child, because her genetic information is identical to that of the father.
They have the wrong child, because her genetic information does not match that of either parent.
They have the correct child, because her genetic information came from both parents.
They have the wrong child, because her genetic information matches only that of the mother.
DNA fingerprinting works because
Most genes are dominant
All organisms contain RNA
The most important genes are different among most people
No two people, except identical twins, have exactly the same DNA

Parents A and B
Parents G and H
Which male is the father of the child?
Male 1
Male 2
