About Twins

Abstract

Twins, unique and similar – oh, the marvel of it all. Consider the fact that twins represent only about 3% of the population. The amazing journey of a set of identical twins begins with one single egg, which splits during fertilization into two eggs with the same genes. Having the same genetic makeup is why identical twins have similar hair and eye color, height, and build. Most often, identical twins also share the same family environment, which means they also have a similar background.
