Snow copies?

[joshuabradley1]

I have been interested in breeding a TUG snow to my normal. I know the first year babies will be 50% Snow ( Copy 1) and 50% normal. The following year breeding the Snows (Copy 1) back to the TUG snow will create 25% snow (Copy 2), 50% snow (Copy 1), and 25% normals. My question is how to tell the copy 2's from the copy 1's in the snows?

TUG Snow is a Dominant trait, there is no visible difference between heterozygotes and homozygotes. You will have to test breed to find out.
