Actually you could have frosties. chin cancels all the yellow fur, and red/orange cancels all the black fur. You get what appear to be white rabbits with brown eyes.
Regarding pattern you would get 50% broken and 50% charlies. 0 solids. So if they LOOK solid, they are frosties, and you just can't see the spots. Or they are REW...
You could also get REW if they both carry that.
You could also get broken/charlie agouti
You could also get broken/charlie black
You could also get broken/charlie chocolate
You likely will not get broken/charlie red or broken/charlie chin. But you COULD.....Lol. Sorry I am aware this is not very specific. The issue is that both could be carrying an albino/REW gene, and if so, that changes many things! If they have a litter, then I will have more guesses about what is going on.
