Leopard Gecko genetics
OK, before we get too far off the topic of Leopard Geckos, I'd like to add something that may help understand the 'hypo' and 'super-hypo' and how it compares to the NORMAL genotype. Since they are all line-bred traits derived from Normals, High-yellow, Hypo-yellow, Tangerine, Hypo-tangerine, Super-hypo tangerine phenotypes are all born looking exactly like Normals. They are a pale yellow color with wide black bands, and as they grow and shed the black banding breaks up into spots, or starts fading... and their body color starts developing into their adult coloration.
Hypos will develop fewer than 10 spots on their body, while the rest fade away, and Super-hypos will lose all of their body spotting, and 'baldies' will lose their head spotting. The final body coloration would make it either a Tangerine or a Yellow/gold. The color, intensity of color, and amount of patterning are all line-bred traits.
Now, Patty's are born a tan color with slightly darker blotches, or 'mottling', that fades as they grow and their final solid color develops. Blizzards are hatched either pure white (sometimes tinged with yellow), pale gray, or pinkish with no body patterning at all. Pattys and Blizzards are not derived from the Normal genotype.
