TONGUE ROLLING

Inheritance

The inheritance of a tongue roller is a disputable subject. Some people say it is controlled by one gene. They also found out that when you get older you start to learn how to roll your tongue. The reason you’re able to do this is because of the environmental factors which are to support the gene which helps you to be able to roll your tongue. I believe it is inherited because both my grandparents on both sides can roll their tongue.
