What is a key visual characteristic noted about the side pattern when comparing a Yellow Belly to a Normal Ball Python?

The side pattern is cleaner, more defined, with reduced markings

A significant aesthetic benefit of the Yellow Belly gene is its tendency to refine the snake's markings. Compared to the intricate, often somewhat smudged or busy pattern seen on the flanks of a normal ball python, the Yellow Belly expression results in cleaner lines and better definition. This effect often manifests as a reduction in the amount of dark patterning present on the sides, leading to sharper edges on the dorsal saddles and a greater separation between the dorsal markings and the lighter ventral area. Breeders strive for instances where the dark markings appear significantly reduced or break up aggressively toward the lower flanks.
