Leopard Gecko morph
Leopard Gecko (Eublepharis macularius)
Patternless white/yellow gecko
The Blizzard locus is a recessive trait that produces a patternless gecko with solid coloration. Homozygous Blizzard (blz/blz) animals lack the normal banded or spotted pattern entirely, displaying a uniform body color that can range from pure white to yellow to dark brown/purple depending on other genetics and temperature. Blizzard is a different gene than Murphy Patternless. Confirmed by complementation testing (crossing Blizzard x Murphy Patternless produces normal-patterned double-het offspring). While both produce patternless geckos, they achieve it through different genetic mechanisms at separate loci. Blizzard is a key component of the Diablo Blanco combo morph.
How to identify it: Blizzard (blz/blz): Completely patternless body. No spots, bands, or markings. Body color varies widely: can be pure white, cream, yellow, gray, brown, or even purplish depending on temperature, age, and other genetic factors. Coloration can shift with temperature (cooler temps often produce darker Blizzards). Eyes are normal (dark with visible iris pattern, unless combined with Eclipse). Distinguished from Murphy Patternless by body color tendency. Blizzards tend toward white/cream/gray while Murphy Patternless tends more yellow. However, visual identification of Blizzard vs Murphy Patternless can be unreliable without knowing parentage. Heterozygous carriers appear phenotypically normal.
Blizzard follows a recessive inheritance pattern, carried on the Blizzard allele (locus Blizzard).
Because Blizzard is recessive, an animal needs two copies of the allele to show the trait visually. An animal with a single copy is called het blizzard (heterozygous). A het animal looks normal but carries the gene, so pairing two het blizzard animals produces, on average, one in four visual blizzard offspring.
Blazing Blizzard
Double homozygous for Tremper Albino and Blizzard. The Blizzard gene removes all pattern, and the Tremper Albino gene removes dark melanin. The result is a solid white to pale yellow gecko with no pattern or markings. Eyes are Tremper Albino type (lighter than normal). One of the most popular "all-white" leopard gecko combos. A key stepping stone morph in the creation of Diablo Blanco.
Banana Blizzard
Double homozygous for Blizzard and Murphy Patternless. Both genes independently produce patternless geckos but at different loci. The combination produces a solid yellow to banana-colored patternless gecko. Warmer and more yellow than Blizzard alone (which tends toward white/cream). The Murphy Patternless gene contributes its characteristic warm yellow tone to the Blizzard patternless base. Confirms that Blizzard and Murphy Patternless are separate genes.
Diablo Blanco
Diablo Blanco is a combination of four traits: Blizzard (recessive), Tremper Albino (recessive), Eclipse (recessive), and Patternless Stripe (line-bred). Created by Ron Tremper in 2006 by crossing his whitest Blazing Blizzard female with a RAPTOR male. The result is a pure white gecko with solid red eyes. One of the most visually dramatic leopard gecko morphs. The name translates to "White Devil" in Spanish. Note: Patternless Stripe is polygenic and tracked in description only.
