What is the vampire power of Bella's daughter?

Spoiler Alert!

Bella's power is a shield against mental attacks, such as mind reading (like Edward), or Jane and Alec's powers of pain or unaware of pain, Zafrina's power (replacing anything in the mind with a picture, therefore the opponent is unsure of where to attack), etc.

A lot of people also wonder how Jasper is able to control her emotions. Jasper's power is linked to the adrenaline glands and such, and is physical not mental.
