The White Ear mutation causes both ears to be white (or mostly white) and typically also causes white front feet and Dutch-like markings on the face and body.

The White Ear genetics are incompletely dominant. To get a true White Ear, you need one Non-White Ear allele (“we”) and one White Ear allele (“We”). Two White Ear alleles (WeWe) gives you much more white on the rabbit (some refer to it as "extreme white ear"), whereas two Non-White Ear alleles (wewe) gives you a a normal, Non-White Ear rabbit.

We: White Ear
we: Non-White Ear

Breeding an "extreme white ear" to a non-white ear rabbit will result in 100% white ear rabbits.

White ear can occur on any base color, though it can be easily mixed up with Charlie brokens and Vienna marked rabbits. A rabbit can have multiple white pattern alleles: white ear + broken, white ear + Vienna mark, broken + Vienna mark, or all three), making it very difficult to distinguish without test breeding.
