Gargoyle gecko morph calculator

Rhacodactylus auriculatus — Gargoyle gecko appearance is almost entirely line-bred — stripe, reticulated and blotched patterning plus red, orange and white base intensity. Only a handful of traits behave like single genes.

Questions keepers ask

Are predicted morph percentages guaranteed in a clutch?
No. Each percentage is a probability for an individual egg. A small clutch can differ substantially from the expected ratio.
Can a photograph prove a recessive het?
No. Record documented parentage, breeding evidence or appropriate genetic testing separately from visual appearance. A possible het remains a probability, not a proven carrier.
Can line-bred traits be predicted with a Punnett square?
Not reliably. Line-bred and polygenic traits involve selection and multiple influences; keep their descriptions in animal records rather than treating them as simple single-gene odds.
