How does the Yellow Belly designation differ fundamentally from a recognized subspecies of *Python regius*?
The Yellow Belly is artificial selection, whereas subspecies reflect natural geographical variation.
The fundamental distinction lies in their origin and taxonomic relevance. The Yellow Belly designation describes a specific morph, which is a variation resulting from intentional selective breeding and human intervention within captivity, thus classified as artificial selection impacting coloration and pattern. Conversely, recognized subspecies within taxonomy are established based on natural, geographical variation found across distinct, naturally occurring populations, often identified through a trinomial name (*Species subspecies*). The Yellow Belly trait alters aesthetics within the single species *P. regius*, while subspecies reflect measurable evolutionary divergence based on geographic isolation.
