The two amelanistic corns are heterozygous for anerythristic. That is the only way that they could produce snows, which is a combination of amelanistic and anerythristic. I would expect more like a 3:1 nonsnow to snow ratio, though.

I think those type 2 anerythristic (AKA charcoal) babies were really anerythristic and not charcoal. That would make the mother heterozygous anerythristic. As none was amelanistic or snow, if you got more than 7 babies, then the odds are greater than 95% that the mother is not heterozygous amelanistic.
