Overview

Our Yellow Belly DNA test for royal pythons detects the two known Yellow Belly variants in the EDNRB2 gene, a gene involved in pigment cell development.

Yellow Belly shows incomplete dominant inheritance. Wildtype animals do not carry a Yellow Belly variant. Heterozygous animals carry one variant and often show richer yellow coloration, typical flank flames, and checkering along the edge of the belly. Animals with two Yellow Belly alleles show the nearly white super form known as Ivory.

Because the heterozygous form can be visually subtle and variable, DNA testing provides valuable confirmation of genetic status. This supports accurate identification and more informed breeding choices.

  • Confirms the presence of the two known Yellow Belly variants
  • Helps identify subtle or difficult-to-judge animals more accurately
  • Supports targeted pairings and better-informed breeding plans
