Which three genes combine to form the famous Bumblebee morph?

Spider, Pastel, and Yellow Belly

The Bumblebee morph is considered a complex or designer combination, illustrating the power of layering multiple visual traits. This specific combination unites the Spider gene, which is responsible for introducing unique pattern distortions, the Pastel gene, which typically boosts the overall brightness of the snake's coloration, and the Yellow Belly gene. The Yellow Belly's contribution in this mix is vital, as it works to clean up the sides of the animal and accentuate the overall vibrancy with its characteristic bright yellow accents, ensuring the resulting animal is more visually striking than a combination lacking that specific clean-sided definition.
