Introduction. Almost any part of the body can be affected and in severe cases, the whole body is covered in thick hair. The causes of hypertrichosis aren't well understood, though there is a form of the disease that tends to run in families. Because animals heterozygous for undesirable or lethal recessive traits often cannot be detected by visual examination, and sometimes exhibit a phenotype that is thought to be desirable, inadvertent selection may help spread genetic .
