How are twins (identical/fraternal) born?

Does the mother really carry two babies at once?

I can understand the capacity of the womb being that great, the human body’s a magnificent thing, but the idea is just so counterintuitive I wonder whether it’s actually possible for a womb to extend THAT far.

Identical twins – Mom has a fertilized egg that splits. Technically twins have the same DNA, but there are environmental factors can change gene expression.

Fraternal twins – there are two (or more) eggs that get fertilized at the same time. Different DNA but the same Momma.
