And since I'm very low on question 1 it works out well that I'm high on 2 and 3.
I finally produced an albino female in 2009 after only a single decade of work and she was also 33% chance het stripe but since I still couldn't afford albinos I couldn't afford to keep her. Selling her was a real shame as I had a good feeling about her pattern. I did keep two of her possible double het sisters though.
