The ability to roll your tongue is a genetically inherited trait. Some people can do it, and others can't. If you can roll your tongue, it simply means that you have inherited that trait. If you can't, then you lack it. It's genetic, and out of your control.

Being able to roll your tongue means you have the genetic trait for tongue rolling, where the sides of your tongue can be curled upwards into a tube shape. This trait is inherited and controlled by a single gene.
