Cumin has entirely solid reds on his pedigree so I'm not expecting surprises from him.
You'd be surprised what recessives can pop up when you cross outside of a rabbit's normal lines. Like generations of black x black breeding that suddenly throws white or chinchilla or tort when crossed out to a new line. You can't tell a full color black from a chinchilla self black by looking at it (unless it inherited the odd chin blue or marbled eyes as well). You can breed two self colors together for many generations, and never know that black was actually a self chin.
I ended up with a white kit and a blue (or maybe even lilac) this year when I crossed a wild gray chestnut to a new black buck. He obviously carries white, though it doesn't show up in the pedigree. The surprise was from my agouti doe, whose line I have never bred to a white. Yet there it is. Someone somewhere came with a recessive albino gene, and has passed it along undetected for decades. I haven't bred for dilute in at least thirty years, only choosing dense color rabbits for all these generations, and suddenly out pops a dilute. Some bunny somewhere along the line has been hiding the dilute genetics for generations, but apparently had no dilute mate for it to express itself until I bred to the new buck, which does have dilute in its distant pedigree. I don't normally cross agouti into the black line, but the doe had exceptional fiber and good color to the skin, which the black buck did not--I was hoping to improve the black fiber in the line I normally only breed black x black.
So, I'm back to the drawing board. My line obviously has a variety of hidden recessives, and I'm going to have to figure out how to weed some of those out, as I'm trying for a black line that is non-agouti, black, full color, dense color, full extension (
aa BB CC DD EE) . Since this litter has two torts (one dense and one dilute), an albino white and a blue or lilac (I haven't had a dilute in ages, not sure which one this one will be), the agouti doe must be
Aa B_ Cc Dd Ee, and the black buck must be
aa B_ _c Dd Ee. I would have never guessed. It's amazing what can hide for generations.
There are several blacks in the litter, which means they did inherit the non-agouti aa, but who knows what else they inherited, I don't think I want to use them in the black line after all.
