At a glance: Panther gecko morphs are captive color and pattern forms of Paroedura picta. Peer reviewed work confirms that adults show different color phases, but no named form has a tested inheritance mode. Striped, patternless, amel, snow and hypo are hobby names.
Panther gecko morphs are the named color and pattern forms of Paroedura picta, a small ground gecko from southern Madagascar. Only one thing about them is documented in the scientific literature: adults in captivity show different color phases. Every named form in the trade is a hobby label, and this page marks each one that way.
The species is better known to keepers as the pictus gecko. For care, size and housing, see the pictus gecko species guide.
What science confirms about pictus gecko morphs
The genome paper on this species in BMC Biology describes it as a laboratory model lizard and shows adult individuals with different color phases. The paper does not describe those phases, and it does not say whether they are inbred strains or ordinary variation. It also does not name any morph or give an inheritance mode.
The same paper notes that captive females lay two eggs about every 10 days all year round. That steady output is one reason the species is common in captivity. It also means a breeder can turn over generations quickly, which is why new looks appear and get names fast.
A written source that tests a pictus color line with breeding crosses does not exist in the sources opened for this page. Anyone quoting a firm mode of inheritance for a named form is repeating breeder reports. Treat those reports as leads, not as established genetics.
Panther gecko morphs index
The table lists the forms most often sold under a name. Each row carries the hobby label because no peer reviewed, university, museum or veterinary source describes it. Descriptions are broad, since breeders use the same words for slightly different animals.
| Morph | What it looks like | Inheritance | Source | Known health issues |
|---|---|---|---|---|
| Striped | A pale or cream dorsal stripe running down the back and tail instead of a broken saddle pattern | Unknown; not sourced | hobby name, inheritance reported by breeders, not independently tested | None sourced |
| Patternless | Reduced or absent dark markings, leaving a plain or lightly marked body | Unknown; not sourced | hobby name, inheritance reported by breeders, not independently tested | None sourced |
| Amel or albino | Lighter body with reduced dark pigment, sold under either name | Unknown; not sourced | hobby name, inheritance reported by breeders, not independently tested | None sourced |
| Snow | Pale, washed out base with faint markings | Unknown; not sourced | hobby name, inheritance reported by breeders, not independently tested | None sourced |
| Hypo | Reduced dark pigment and a cleaner, lighter pattern than a typical animal | Unknown; not sourced | hobby name, inheritance reported by breeders, not independently tested | None sourced |
Existence is the second gap. No authoritative source lists these names, so it cannot be confirmed that each one is a stable, distinct line. Names may overlap, and one animal can be sold as two of them.
Wild type color and pattern variation
The typical animal is a brown to tan gecko with a broken pattern of pale and dark blotches, and the genome paper photographs adults in more than one color phase without naming them. That look is what the phrase pictus gecko colors usually means. Individuals vary in how pale the base is and how dense the markings are, even without a named morph.
Variation between siblings is normal, so a single animal that looks unusual is not proof of a morph. Only repeatable results from planned pairings show that a trait is heritable. Without that, a striking gecko may simply be a wide swing within the normal range.

Genetics that are actually known
Two genetic facts are documented. A 2024 cytogenetics study in Animals (MDPI) found 2n = 36 chromosomes in Paroedura picta, mostly acrocentric with one metacentric pair. It found no differentiated sex chromosome pair in the female it examined.
A review of sex determination in geckos by Gamble in 2010 reports balanced sex ratios in this species across incubation temperatures. That is consistent with genetic sex determination rather than temperature dependent sex determination. In practice, incubation temperature is not a tool for choosing males or females.
Neither result says anything about color genes. No color locus has been mapped for this gecko in the sources opened here. To learn how recessive and dominant traits are predicted, read the morph genetics page.
Health and morphs
No health problem has been linked to a pictus morph in a source opened for this page. Other reptiles do have traits tied to health, so the absence of a source is not proof of safety. It only means the question has not been tested here.
Judge a gecko on its condition, not its label. Look for a rounded tail base, clear eyes, an alert stance, steady feeding and clean vents. A reptile veterinarian can check an animal before purchase, and the Merck Veterinary Manual reptile section is the standard clinical reference they use.
How to evaluate a named morph
Ask the seller for the pairing that produced the animal and for photos of the parents. A real line repeats: the same look should appear across clutches from the same parents. If the seller cannot show that, the name is a description rather than a line.
Prices and rarity claims are marketing until a trait proves out in breeding. Expect the same species care needs regardless of look. The wider database at the morph database explains how this site labels evidence for every reptile.

Frequently Asked Questions
Are panther gecko morphs the same as pictus gecko morphs?
Yes. Both names refer to Paroedura picta, and keepers use them interchangeably. Some also call it the ocelot gecko, though that name is used loosely for related ground geckos.
Is 2n = 36 the same in every ground gecko?
The study reported 2n = 36 for Paroedura picta and described it as likely the ancestral condition within its species group. Other Malagasy ground geckos in the same study differ, so do not apply this number to related species.
Can I tell the sex of a pictus gecko by its color?
No source ties color to sex in this species. Sex is genetic rather than set by incubation temperature, so eggs cannot be steered by heat. Adults are sexed by anatomy once they mature.
Does a lighter gecko need different care?
No care difference is documented for any named form. Housing, heat and feeding follow the species guide. A vet visit is the right step if a pale animal shows poor eyes or skin.
How fast do new pictus lines appear?
Fast, because females lay two eggs about every 10 days in captivity. Short generation times let breeders fix a look quickly, though a fixed look is still not the same as tested genetics.
