Beside this, is tongue rolling genetic?

Tongue rolling is the ability to roll the lateral edges of the tongue upwards into a tube. Rolling the tongue into a tube shape is often described as a dominant trait with simple Mendelian inheritance, and it is commonly referenced in introductory and genetic biology courses.

Subsequently, question is, why can I roll my tongue? The reason we couldn't all do it, we were told, is because it is a simple genetic trait. You had either inherited the right variant of the tongue-rolling gene or you hadn't. And if you hadn't, you would never be able to do it.

Keeping this in view, what percentage of people Cannot roll their tongue?

The only explanation is that tongue rolling is not controlled by simple genetics as everyone first thought. Further studies even found that about 10 percent of those people who can't roll their tongue can be trained to roll it.

What gene is responsible for tongue rolling?

Tongue-rolling is caused by a dominant gene which we can call T." Pretty specific, yet untrue, says McDonald. The misinformation began in 1940, when geneticist Alfred Sturtevant wrote that tongue rolling was a genetic trait that relies on one dominant gene.
