In the ARBA SOP, the color orange is listed as wideband, but oddly enough, an orange rabbit doesn't have the wideband gene, in essence it is an agouti tort. Cream, the dilute version of orange, and Frosty, the chinchilla version of orange, are also considered wideband in the SOP but are not truly carriers of the wideband gene.
The wideband gene is NOT dominant, so many people like to say it is recessive. I disagree that it is a recessive gene. Wideband is what is called a co-dominant gene. This means that if your rabbit has the gene it will show through to some extent. Mostly through belly color, but you can also tell by booting in the brokens sometimes. That being said, the gene does not FULLY express unless you have 2 copies of the wideband gene.
If 2 copies of the Wideband gene is ideal, then why do we breed to non-wideband rabbits? Type. Our goal is to make reds of quality, so we need to breed to our other show lines in order to improve on type. This means that at this time we have a lot of "reds" with only one copy of the wideband gene, which means their color is visibly red in most cases, but not optimally red (especially in relation to the cream belly color). If you question the genotype of one of our sale rabbits, ASK. I will give you an honest answer of single copy, 2 copies, or I don't know/could go either way.
