I first made this list around 2012 as handwritten notes after reading Saga’s explanation of the genetics system. I created it to help myself quickly figure out which cats to use when trying to pull certain traits.
Over time, I stopped using it because I got more comfortable making those decisions on the fly. Today, I decided to refine it, turn it into a digital version and share it through a Google Document.
I’m hoping it can help others. I’ll continue reviewing it to catch any mistakes, and I’d really appreciate any feedback or corrections from anyone who uses it.
This isn’t meant to be a definitive guide. If you decide to use it, please review it carefully and rely on your own judgment and experience.
Note: I find it easier to think of traits using the letters A, B, C, D (ordered by dominance). This system makes things clear in my mind and helps me organize the possibilities logically, but I understand that not everyone may be comfortable with this setup.
