Yeah, pretty much if you breed two rabbits of the color you want, you will almost certainly get that same color for most of the litter. It's possible for them to carry for other colors:
- martens can carry a self gene, which I think would show up as black, although that black would have the chinchilla gene instead of full color, so not the best genetic makeup)
- martens can also carry the sable gene (not sure how it shows up with the otter gene, though...probably just adds the white belly and other markings, which would be unshowable)
- any could potentially carry himalayan or REW
But, if you get the rabbits from reputable breeders, they should be able to tell you what other colors each carries.
If you want to look at the genetic markup:
Silver Martens are at-B-c(chd)-D-E-
Siamese Sables are aa B-c(chl)-D-E-
Smoke Pearls are aa B-c(chl)-ddE-
so, if you can't find parents of the same color, you can "make" the colors:
-Silver Marten from black otter with a chinchilla or silver marten parent X chinchilla with a black otter, self black, or silver marten parent
-Siamese Sable from blacks with sable or siamese sable parents
-Smoke Pearls from Siamese sables with smoke pearl parents, or blues with siamese sable or smoke pearl parents
I'm sure there are a couple other ways to get them, but those are the most obvious ways.
