TLDR: Identical twins aren't clones, just near identical. Mabel and Dipper could be identical but admittedly probably aren't because it's unusual for identical twins to not be the same sex, but Ford and Lee probably are identical as they could easily have the same genetic makeup, just different phenotypes. Why are the Stans "probably identical"? They have different numbers of fingers! And clearly are very different looking. As they grow up identical twins begin to look different. Not to mention the original embryo splits in two which is why they are identical. However there can be minor varations from thereon. Which is why identical twins like Tia and Tamara Mowry are identical with minor differences. In their case on has a mole on her cheek and the other has a mole on her neck.
