What does 50% het or 66% het mean?
Both percentages reflect the statistical probabilty that each egg, not the clutch as a whole, will be some genotype xyz. If you breed two snakes that are both normals het amel together, the resulting statistical probabilty will be as follows: 1/4 amels, 1/4 normal, 1/2 normal het amel. Disregard the amels as they are showing the trait and cannot be het for it, and you are left with all normals, some het for amel and some not. Theoretically 1/2 out of 3/4 of the normals will be het for amel. 0.5 / 0.75 = 0.66667%. The same holds true regarding 50% het. A normal x normal het amel will give all normal offspring, 50% being het for amelanism.
