Essentially, yes. I'm surprised they included the hypo since often it's felt to be line bred, but I do see that in the calculator they list "hypo" and consider it dominant (though I see they give it a 50% chance of occurring overall, so I guess they feel that the hypo male has only one hypo gene). Overall, they are saying that all the offspring will be het eclipse and het Tremper and that 50% of them will be Mack snow.
