And Twiiiiiiinnnsss

So twins are pretty extraordinary as you might already know. But there's more to twins than you probably don't know.

To start off most people just know of fraternal and identical twins, but there are actually 7 types of twins including half-identical, mirror image, mixed chromosome, superfecundation, and superfetation twins. Twins aren't always born on the same date. One set of twins were born 85 days apart. It's possible for twins to have different fathers which is known as "heteropaternal superfecundation" where the mother releases two eggs that are fertilized by two different fathers. Identical twins have almost identical brainwave patterns tend to know what the other is thinking and feeling and even if separated at birth will tend to be identical in behavior still. Identical twins can also have different sexes, skin color, and other variations but will always have different fingerprints.
