Specter (EDNRB2-related) - Ball python

This analysis detects the Specter-associated c.G2601C (R315P) variant in the EDNRB2 gene of the ball python (Python regius). Specter is part of the Yellowbelly series, also known as the Yellow Belly complex.

An animal without the tested variant has a wildtype result. A heterozygous animal carries one copy of the variant and may show a subtle or variable visual expression. A homozygous animal carries two copies and is associated with the Super Specter form, which typically shows a lighter, moderately reduced pattern, often with two dorsal stripes.

When a Specter allele is combined with a Yellow Belly allele, this is associated with the well-known Super Stripe. This form is usually recognized by a striking, fairly symmetrical longitudinal stripe and relatively clean sides.

• confirms the presence or absence of the tested Specter variant
• supports interpretation of subtle or difficult-to-identify animals
• helps guide breeding plans within the Yellow Belly complex

This test is particularly valuable for breeders and keepers seeking greater confidence in identification, selection, and interpretation of animals with a possible Specter-related phenotype.
