What is the "orange" in Orange Kush?

[MastaChronic]

struck out.

Has nothing to do with mutation, just back-crossing strains to bring out a prominent orange look.

i was going back a little farther than just back crossing, i was going waaaaaaaaay back to when there were no orange hairs and then *boof* genetic mutation, orange hairs. its a dominant gene and overpowered the weaker gene that controls hair color and eventually developed into a stable gene.
just like when a black haired human crosses with a blonde haired human the offsping is most likely to be black or brown hair because of the dominant gene.
this is sort of like mendelieves experiment with the peas.
