>If the offspring were indeed charcoal though, what would that change about the amel father and normal mother.

If the offspring were charcoal, then the amelanistic father would be heterozygous charcoal, and the normal mother would be heterozygous charcoal.

The amelanistic male was used in both matings. To get all the reported babies, he would have to be amelanistic, heterozygous anerythristic, heterozygous charcoal. This would produce snows in the first mating with an amelanistic, heterozygous anerythristic female and charcoals in the second mating with a heterozygous charcoal female.

If the charcoal babies were actually anerythristics, then both the amelanistic male and the normal-looking female are heterozygous anerythristic. If the snow babies from the first mating were actually blizzards (amelanistic, charcoal) instead of snows (amelanistic, anerythristic), then both amelanistic parents are heterozygous charcoal.

So there you have it -- three possible scenarios.
1.
Male: amelanistic, heterozygous anerythristic, heterozygous charcoal
Female 1: amelanistic, heterozygous anerythristic
Female 2: heterozygous charcoal

2.
Male: amelanistic, heterozygous anerythristic
Female 1: amelanistic, heterozygous anerythristic
Female 2: heterozygous anerythristic

3.
Male: amelanistic, heterozygous charcoal
Female 1: amelanistic, heterozygous charcoal
Female 2: heterozygous charcoal

I don't know how to tell anerythristic babies from charcoal babies without a pedigree. If you do, please tell me.
