title: Genetic variation of esterase D (EsD) polymorphism in Indian populations.
abstract: Data are presented on the phenotypes and gene frequencies of esterase D (EsD) polymorphism in various endogamous caste groups of Patiala and Faridkot districts of Punjab, north-west India. The frequency of the EsD2 allele in these groups varies from a minimum of 0.157 in Khatris to a maximum of 0.253 in Ramdasia Sikhs, a range quite typical of the north Indian populations. Examination of the available data on esterase D system in indigenous populations demonstrates the existence of a north-south cline in the distribution of the EsD2 allele in India.
