Chinese crested dog

Abstract

The Chinese crested dog is devoid of hair except for the crown of the head, lower part of the limbs and tail. The breed is produced by a dominant gene for hypotrichosis (Hr) In combination with the gene for long hair (I). The homozygote HrHr is a prenatal lethal, hence the Chinese crested dog is an obligate heterozygote. The long haired segregants, ++//, are known as powderpuffs.
