How does the Yellow Belly gene typically enhance combined morphs?

Lightens ground color and cleans up pattern lines

The Yellow Belly gene is highly valued in breeding projects because of its strong additive effect when combined with other genetic mutations, both recessive and co-dominant. Its primary function in these combinations is that of an enhancer; it actively works to lighten the existing ground color of the resulting snake. Furthermore, it often results in a cleaner presentation by sharpening the lines where the dark segments meet the lighter areas, reducing the 'smudging' seen in some base morphs. For example, when paired with Pastel or Mojave, the resulting snake displays higher saturation of base colors and patterns that are more defined than if those genes were expressed individually.
