HHaA

HHaA is a human pseudogene believed to be responsible for fur-like body hair. In humans the gene has become deactivated making it a pseudogene, however there is variation in the degree of body hair among human beings and occasional examples have been found of people where the gene is active leading to very thick body hair as a result.[1]
