Ball Python morph
Ball Python (Python regius)
Visual TSK Axanthic. Homozygous at TSK axanthic locus. Grayscale coloration. Tends to hold color better with age than some other lines.
Reduces yellow/red pigment, producing a grayscale animal. TSK line was established by The Snake Keeper. Incompatible with VPI, Jolliff, and MJ axanthic lines, confirming a separate locus. TSK line tends to hold its grayscale coloring better with age compared to some other lines, though browning out can still occur.
How to identify it: Grayscale blacks, whites, and silvers. Similar to VPI Axanthic but reportedly holds color better with age. Normal ball python pattern shape.
TSK Axanthic follows a recessive inheritance pattern, carried on the Axanthic (TSK Line) allele (locus AxTSK).
Because TSK Axanthic is recessive, an animal needs two copies of the allele to show the trait visually. An animal with a single copy is called het tsk axanthic (heterozygous). A het animal looks normal but carries the gene, so pairing two het tsk axanthic animals produces, on average, one in four visual tsk axanthic offspring.
