I have a 7 egg clutch that just hatched from Albino X Het-Albino (suppose to be a 100% Het) This female was strickly bred to the Albino male, all 7 hatchlings are normal Hets, no Albinos from a 7 egg clutch.

I realize there is a very tiny small chance of not producing visuals from a 7 egg clutch. I would tend to say she is not a Het

Can anyone well versed in math or stats provide the % figure of not producing Albinos from a 7 egg clutch.

Much appreciated
