correction: with the twin thing, you're thinking of epigenetics. If bending is just genetic, then you can't have twins where only 1 is a bender/ each twins bends a different element. But we SEE those earth kingdom twins where one earthbends and the other can't. On the other hand, it could be gentic/biological. So you have a gene that gives you bending potential, but your prenatal environment determines whether this gene is expressed.
