A 50% chance het albino that is also 50% chance het piebald has a combined 25% chance of being double het for albino pied.
I bred a 4/9 chance double het albino pied male (66% het albino and 66% het pied) to a het albino female and when he didn't prove het albino I kept the 33% chance het pied and 50% chance het albino daughters with the pied markers. The first one to breed proved het pied. I'm holding back 2.1 of her pied babies in the hopes they hit their 25% chance het albino. Oh, and they are also 12.5% chance het VPI axanthic from their dad, lol. Can you tell I like possible hets?
