Genetic test for the GCH2-related Axanthic variant in ball pythons.

Overview
This genetic test assesses the GCH2 c.520C>T variant associated with Axanthic in ball pythons. Axanthic animals lack the usual yellow pigmentation and therefore show a cooler grey-to-black appearance while retaining the underlying pattern. The result helps determine whether the tested animal is free, carrier or positive for the tested variant. Other genetic factors and other axanthic lines can still influence the final appearance.
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 Axanthic variant detected
This animal does not carry the tested GCH2-associated Axanthic variant. This result therefore does not support this specific variant as the explanation for the tested animal's Axanthic line. Other axanthic lines or other genetic factors can still influence the final appearance.
Allele combination: Carrier of the tested Axanthic variant
This animal carries one copy of the tested GCH2-associated Axanthic variant. It can pass this variant to offspring. One copy alone is usually not enough for the full Axanthic colour outcome, and other axanthic lines or other genetic factors can still influence visible expression.
Allele combination: Axanthic-associated genotype detected
This animal has the tested GCH2-associated Axanthic genotype. That supports the presence of the analysed Axanthic variant and means this variant will be passed on to offspring. Other axanthic lines and other genetic factors can still influence the final colour outcome.
