Incidence of cleft chin among the Adi and Apatani of Arunachal Pradesh, Northeast India.
The occurrence of cleft chin was studied among five endogamous groups (Padam, Minyong, Pasi, Gallong, Apatani) of Arunachal Pradesh, Northeast India. The incidence of this trait is low in all the groups. Thus, the populations are characterized by low frequencies of the gene Cl. Bisexual difference is significant only among the Minyong. While compared with other populations from Northeast India, the Mongoloid populations were found to be distinct from the only caste population, which has been investigated so far.
