REW or BEW dominant?

[Nello'sHops&Lops]

I have a kit that I really expected to be a BEW but their eyes opened enough today that I'm pretty confident in saying it's a REW


That just kind of got me to thinking of which is dominant? If a kit is both cc AND vv which would be expressed? Or would you get purple eyes or something?

Albino REW trumps BEW, as no color (not even in the eyes) is produced. So REW is dominant, and even though the kit may be vv as well, only the cc will show. However, the vv kit can still pass along the Vienna gene.

The cc genes are on the color locus, while the vv genes are on the vienna locus. Sine cc combination is domiminant to aĺl other alleles, the rabbit who gets two copies of cc will be a REW regardless of the other locus groups.

If you bred a BEW to REW, and got any REWs, then the BEW is genetically an albino carrier. If the BEW had two copies of the albino gene, it would be a REW, and hide the genes that make it a BEW.

Breeding a BEW to a REW should throw all colored kits carrying one REW gene. The good news is that all the kits would be vienna carriers. So breeding the offspring together would give colored kits, BEWs, and REWs.
