Do You Have One Of These RARE Genetic Traits?

 For most of us, the study of genetics is pretty much rocket science. But in reality, all of us can learn a little about this fascinating science by taking a close look at ourselves and other humans. Without a fault, you’ll find traits that are genetically inherited - like your eye color, hair color, and even your ability to whistle!
Did you know, for example, that only 14% of the world population can whistle? So. if you do, that makes you quite unique. You might have several of such rare genetic traits that make you unlike most of the population! Take a look at several of such rare genetic characteristics in this article.

1. Only 27% of the world population can raise one eyebrow since birth.

This phenomenon is known as heterochromia, and it can be partial (when only part of the eye is differently colored) or complete (when the entire eye is of a different color). This trait is actually more common in some animals - famously, husky dogs have heterochromia often.
