Genetics Test 2 Review

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.
