Most morphs are simple recessive (Amelanistic, Anerythristic A, Charcoal/Anery B, Hypomelanistic, Caramel, Lavender, Lava, Sunkissed, Diffused, Motley/Stripe, Cinder, Toffee, Terrazzo). Tessera and Palmetto are incomplete dominant. Polygenic line-bred appearance traits (Miami, Keys/Rosy) and selective-color lines layer against the Mendelian loci. Bloodred is a selectively-bred line built on Diffused plus Masque and red-enhancing modifiers.
Species reference
OriginNative to southeastern United States. Range covers New Jersey south through Florida and west through eastern Texas. The species occupies pine barrens, hardwood hammocks, and rocky hillsides.
