Identical twins, also called monozygotic twins, develop from a single fertilized egg, or embryo. Depending on when that embryo splits, they might also share the same placenta and amniotic sac.

Cloning is a biotechnological process that involves creating genetically identical copies of an organism or cell. In essence, a clone is an exact genetic replica of the original organism or cell, ...

We're made up of around a hundred trillion cells, all coming from just one single fertilised egg. Within hours of fertilisation, this new cell, called a zygote, divided into two identical cells.
