Long-haired donkeys produce thick, shaggy coats. Two allele variants inherited in an autosomal recessive fashion have been identified as causing this phenotype.
White spotting patterns occur in many donkey breeds and are similar to those of horses in that the amount of white can range from a few white hairs to an animal that is almost completely white. Two variants have been identified in donkeys that contribute to white patterning (W and Wˢ).
