With a het to het breeding the odds that each individual, normal appearing snake, in the litter will be heterozygous is always 66% for each individual. It does not make any difference how each of the rest of the litter turn out. The 66% possibility applies to each individual in the litter separately. Its like rolling a one-thirds / two-thirds set of dice for each individual in the litter one at a time to determine whether it will be het or not. There is no connection between individual littermates as far as whether they will be homozygous or heterozygous. Additionally, the larger the litter, the closer the numbers will come to the 66% mark. Conversely, I know of one small litter of boids from a het to het breeding that produced 75% albinos. Just my take on it.
