How does the Yellow Belly influence the typical 'alien head' markings on a young snake's sides (laterals)?

The alien head markings often seem less defined or contain more internal lighter coloration compared to a normal counterpart

When observing the lateral scales on a young, single-gene Yellow Belly, the pattern elements, including the characteristic 'alien head' markings, show visible alteration due to pattern reduction. Instead of possessing the dense, clearly defined dark outlines found on a normal Ball Python, the Yellow Belly's pattern elements appear less dense overall. Specifically, the internal areas of these markings often exhibit more of the bright, enhanced ground color showing through, making the overall appearance of the alien head less defined or more broken up. This allows more of the luminous yellow or orange ground color to dominate the sides of the snake, contributing to the cleaner overall look.
