Genetic test for Spark (EDNRB2-related) - Ball python.

Overview
Spark is an incompletely dominant ball python (Python regius) morph within the Yellowbelly/Super Stripe complex. This DNA test detects the EDNRB2 candidate variant p.L152F, a variant strongly associated with the Spark phenotype. A wildtype animal does not carry this variant, a heterozygous animal carries one copy, and a homozygous animal carries two copies; in the hobby, the latter 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 particularly useful for reliable identification, breeding selection, and targeted pairings, for example in Puma projects.
Included subanalyses
This analysis includes the following subanalysis:
Phenotypes
Allele combinations & result interpretations
Below, for each tested locus, you will find the possible allele combinations that may be reported within this analysis, together with a brief explanation of their genetic meaning. The interpretation of possible interactions between different loci is included in the report, but is not shown here in full because that would lead to too many combinations on this page. The final expression may also depend on other genes and their interaction.
Allele combination: No tested Spark variant detected (GG)
This animal does not carry the tested EDNRB2-associated Spark variant. Other alleles in the Yellow Belly complex or other colour and pattern factors can still influence the final appearance.
Allele combination: One copy of the tested Spark variant (GC)
This animal carries one copy of the tested EDNRB2-associated Spark variant. One copy can already influence colour or pattern in this series and can be passed on to offspring. The visible result can still vary, especially in combination with other alleles in the Yellow Belly complex.
Allele combination: Two copies of the tested Spark variant (CC)
This animal has two copies of the tested EDNRB2-associated Spark variant. That supports stronger expression of this specific allele and this variant will be passed on to offspring. The final appearance can still vary because of other colour and pattern factors.
