Hi Bradonfb,
so if you have an albino breed to a Mack snow you will produce
50% Mack Snow and 50% normals. They all will be het for albino, because the albino i rezesiv and the Mack Snow is a co-dominant gene.
The easiest way to produce the Mack Snow Albino is to breed the Mack Snow back to the albino. Than you have a 50% chace to get a albino and also a 50% chance that it is a Mack Snow, or others said you will get:
25% normal het albino
25% albino
25% Mack Snow het albino
25% Mack Snow Albino
So i think that's your best chance, but maybe i be wrong. If somebody else have a other idea please tell.
greetings tomy
