Spark (EDNRB2-related) - Ball python

The Spark DNA test for the ball python (Python regius) detects the EDNRB2 candidate variant p.L152F, a genetic variant strongly associated with the Spark phenotype within the Yellowbelly/Super Stripe complex.

The result distinguishes between animals without this variant, animals carrying one copy, and animals carrying two copies. A wild type animal does not carry the variant. A heterozygous animal carries one copy and can pass the Spark trait to its offspring. A homozygous animal carries two copies; in the hobby this is commonly referred to as Super Spark.

Because Spark can visually overlap with related alleles such as Yellow Belly, Specter, Gravel, and Asphalt, genetic confirmation is especially valuable. This test supports reliable identification, informed breeding selection, and more targeted pairing decisions, including within Puma projects.

• Detects the Spark-associated variant
• Helps distinguish between visually similar morphs
• Supports reliable breeding selection and planning
• Provides added confidence when interpreting complex combinations
