Tiger Crested Gecko Breeding: What Polygenic Really Means
Tiger crested geckos are polygenic, not Mendelian. Learn what that means for your pairing outcomes, pattern selection, and long-term breeding strategy.
TL;DR: Tiger pattern in crested geckos is polygenic, so Punnett squares do not apply and two Tiger parents will not produce consistent Tiger offspring. Q: Are tiger crested geckos a proven Mendelian morph? A: No. Tiger is a polygenic trait, meaning it is controlled by many genes with additive effects, not a single locus. You cannot use a Punnett square to predict Tiger offspring ratios. Pattern quality improves through consistent selective breeding over multiple generations.
