California rabbits producing solid black kits?

[Mara]

So a friend of mine has several litters of pure black kits, that were out of pure California rabbits. I know they were California color for at least 3 generations. Now suddenly solid black pops out?

My first thought would be that an unexpected buck got involved somehow. Perhaps a child swapped rabbits around, or a loose buck managed to breed a few does through cage wire. Several litters all the same color to cali does does suggest it's probably the work of one buck who doesn't have any recessives at his c locus.

Yup, what Zass said!

Californian to Californian = 100% Californian unless they're REW. Only way to get black outa that is from an outside buck.

I've had someone trying to figure out how a tort x tort litter is half black, they're still being persistent in saying it's a tort x tort litter. Which is another impossible litter.

Can you post pictures? Something isn't right. Perhaps one of your cali rabbits is an ermine?
