Is this rare?

I was going through a bag of romaine lettuce I had got at the store and found a leaf that seemed to have sprouted two tips and I was wondering if this is common or not?

Two points that complements one another: first what we see is the leaf of a plant (lettuce) and second, leaves don't usually have stem cells (meristem), lettuce is one of them. The tissue of plants that can differ and become any part of it. I'm pretty sure that this can't be caused by any local damage through growing but in fact is a defect in protein sintesis during mitosis in other words, a mutation. Correct me if im wrong, but for me its very rare.
