 FACT: When Amy Irving is talking to Emily Bergl in the ruins of the  old school, she tells Emily that her telekinesis is a recessive gene  disorder, which was passed on from her father. However, since Emily  is a female she has 2 X chromosomes, therefore her mom would have  had to be a carrier of that gene also for it to show up in Emily, or  she would just be a carrier also and her telekinetic trait would not  show up.
