One Eye, Two Colors
The beauty of imperfection shines forth in this genetic condition. The mystery of an eye having two varying colors. Science calls it Heterochromia. This is a condition that affects both eyes to have different colors, but where one eye has two different colors, this condition is known as sectoral. The sectoral person has a fictional character look, but in reality it's not.
Jointless Finger
Take a glance at your hand and imagine it without a joint. A man was born with this genetic condition known as congenital trigger finger where his right hand does not have joints in any of his fingers. The condition has made the man have a soft hand that doesn’t bend. The condition is not as rare as you think; 3.3 out of 1000 babies get it at birth.
