Yes but you need a larger pool to start seeing any consistency with those averages. Here's an example from 1 snake and since in the earlier hypotheticals we're putting a het to her, there's no visual way of telling if we had a crap out on the odds or not until we raise animals up and prove them out.
Pastel Female: in these 3 seasons, none of the sires carried the pastel gene
clutch 1) 3/5 snakes with pastel gene 60%
clutch 2) 6/7 snakes with pastel gene 86%
clutch 3) 0/6 snakes with pastel gene 0%
Average pastel gene passed on from these 3 clutches, 50% - right on the money. Which isn't really what I expected from a smaller sample size but it still works to my point. You can kill the odds in a single clutch, the odds can kill you, or anything in between. The more clutches you throw into the pile, the closer you will come to seeing the proper averages.
