Leopard Gecko morph
Leopard Gecko (Eublepharis macularius)
Homozygous recessive at the Murphy Patternless locus (mp/mp). Hatchlings show a faint pattern that fades completely by adulthood. Adults are uniform yellow to greenish-yellow, sometimes with a lavender cast. Warmer coloration than Blizzard (which tends white/cream/gray). Different gene than Blizzard. Confirmed by complementation testing. Discovered by Pat Murphy. One of the original leopard gecko morphs from the late 1980s to early 1990s. Component of the Ember combo morph.
The Murphy Patternless locus is a recessive trait that produces a patternless gecko, distinct from the Blizzard gene. Homozygous Murphy Patternless (mp/mp) hatchlings emerge with a faint pattern that fades completely as the gecko matures, resulting in an adult with uniform coloration. Typically yellow to greenish-yellow with a subtle lavender tint on the body. The lack of pattern combined with the characteristic yellow-green tone distinguishes Murphy Patternless from Blizzard (which tends toward white/cream/gray). Murphy Patternless is a component of the Ember combo morph (Murphy Patternless + Eclipse + Tremper Albino).
How to identify it: Murphy Patternless (mp/mp): Hatchlings show a faint banded or mottled pattern that fades progressively and is typically gone by adulthood. Adults are uniform yellow to greenish-yellow, sometimes with a lavender cast. No spots or banding. Color is generally warmer and more yellow than Blizzard. Head may retain slight color variation. Tail color tends to match body color. Heterozygous carriers appear phenotypically normal with standard patterning.
Murphy Patternless follows a recessive inheritance pattern, carried on the Murphy Patternless allele (locus Murphy).
Because Murphy Patternless is recessive, an animal needs two copies of the allele to show the trait visually. An animal with a single copy is called het murphy patternless (heterozygous). A het animal looks normal but carries the gene, so pairing two het murphy patternless animals produces, on average, one in four visual murphy patternless offspring.
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.
Ember
Triple homozygous for Murphy Patternless, Eclipse, and Tremper Albino. Essentially the Murphy Patternless equivalent of RAPTOR. Where RAPTOR uses Blizzard/Patternless Stripe for pattern removal, Ember uses Murphy Patternless. The result is a solid yellow-bodied gecko with solid red eyes. The yellow body color comes from the Murphy Patternless warm yellow phenotype combined with Tremper Albino melanin reduction.
