I've wanted to make a selective breed for years. I was working on one in 2006 that I'd named Persal. So I finally wrote that out. It's not super complex, basically a Persian with alley markings.
Persals
Head: Persian required
Ears: Persian
Body: Persian
Legs: Persian
Feet: Persian
Tail: Persian preferred, Chinichilla Persian also accepted
Coat: Persian, Alley, or Siamese (for the colorpoint)
Markings: Alley, may also include Persian (from
Ferality's OW), or B&W
Personality: Persian or Alley preferred, any accepted
I did try to breed Persian/Alley/Chinchi/BW but I couldn't isolate the Chinchi tail and breed true with all the other features. I'm sure it's possible I just wasn't able to achieve it from scratch.
