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 identicsl"? They have different numbers of fingers! And clearly are very different looking.
