Your plant is called a trifoliate. Its fairly common. I actually have one myself right now. They are poor producers and will branch and form in very strange ways. I never topped mine and now have a plant with two colas instead of the normal one. Plus, as it grew it did weird things with the foliage. Uneven sets, one branch on one side of the plant and no matching branch. Leaves with inconsistent numbers, and even some leaves that were deformed and were webbed together. Best advice I can give you is to grow it out and smoke it. Might as well. But this is certainly not a plant for breeding purposes at all. The trait will be passed on.
