As has been stated, there are no definites. Here are two examples of the odds not working in some clutches that I have produced.
1) Last year I got 7 eggs from an Albino bred to a Het Albino. 1 egg went bad, leaving six. The odds say that I would get 3 Albinos and 3 Hets. Well, we got 5.0 Het Albinos, and 1 Albino (severly deformed and died half way out of the egg)

2) This year I bred a Het Caramel to a Het Caramel (this is the breeding that you were asking about) We got 5 eggs. That computes to 1.25 Caramels. Well we got 2.2 Caramels and 0.1 Poss. Het. Caramels.

So, one year I beat the odds, and one year I lost to the odds. It's all in the roll of the dice.
