The W locus determines whether a rabbit has wideband.
No Wideband (W_)
Most colors lack the Wideband gene. These are normal colored rabbits. Sometimes a rabbit may look like they have wideband, but are simply high rufus. Some color groups may also be referred to as 'wideband,' but are not genetically true widebands (they don't technically have the wideband gene). For example, Orange is not genetically a Wideband color. It can have Wideband, but this is usually quite rare unless deliberately bred.
Non Wideband Colors
Rabbits with the Wideband gene may have a much deeper, redder tone on the underbelly. Wideband is known to widen the band in the hair shaft of colored rabbits (such as agouti pattern and tan pattern rabbits). The effect is most noticeable in tan pattern where wideband is capable of turning an Otter with creamy to white markings into a Tan with orange-red markings instead.
Although it is possible to have an Otter with bright red markings that look like a Tan or a Tan with creamy, washed out markings that look like an Otter with the right rufus modifiers, one of the major distinctions is the undercoat on the belly. On a Black Otter, the undercoat is a slate blue (in the hair shaft) whereas a true wideband Tan is colored all the way down the hair shaft (no undercoat). This is due to the wideband gene eliminating the undercoat.
- True wideband isn't to be mistaken as a color group! Sometimes, colors are referred to as 'wideband' as a group when they actually aren't genetically wideband. For example, most Orange
rabbits are not genetically wideband. In fact, many Reds
are not wideband either (though some are). The only color that is almost always wideband is Tan
(as opposed to the color Otter
, which is the non-wideband version of a Tan).
