Percentages are what each hatchling has a chance of being, not a promise about the clutch. A clutch of six can come out any way at all.
Worth knowing. Melanistic garter snakes also occur naturally in some wild populations, particularly around the Great Lakes, where dark animals warm faster in a cool climate. The trait in the hobby comes from those populations rather than from a mutation that arose in captivity.
Worked out by treating each gene separately and combining the results, which is how these are inherited. Inheritance for Common Garter Snake morphs is established by breeders through repeated crosses rather than published genetics, except where a morph page says otherwise — how this is put together.
