Immunoglobulin (GM and KM) allotypes in the Sikh population of India
The populations of India are genetically diverse, both within and between geographic regions; immunoglobulin (GM) allotypes provide important information on genetic differences between populations, since the frequencies of combinations of allotypes (termed “haplotypes”) vary dramatically among ethnic groups. As part of a project to assess genetic diversity among defined Indian populations, we have examined eight GM allotypes in a sample of 101 un…
Demography of the Juang tribal population of Orissa
Demographic analysis of genealogical data collected in 1954 for 23 Juang villages was undertaken employing indirect estimation techniques and computer projection methodology. Results indicated that this group did not feature the historically high fertility levels associated with Indian tribal groups, although fertility was higher than previously reported for the Juang. The population did feature a mortality differential, with worse mortality cond…

The Delineation of Fertility Strategies in a Tribal Population of India: The Koyas of Koraput District, Orissa
Demographic data collected for a tribal population of India, the Koyas of Koraput District, Orissa, are examined in light of two models of reproductive behavior associated with the economic value of children: (1) the replacement effect; and (2) son survivorship motivation. Retrospective parity histories of Koya women reveal a higher completed parity level for women who experienced infant/childhood mortality, suggesting the presence of these ferti…

Immunoglobulin (Gm) allotypes in a sample of Canadian Ashkenazic jews
Gm typing on the serum specimens of 507 Ashkenazic Jews (predominantly of Polish‐Russian ancestry) from Toronto, Canada has established the presence of haplotypes Gm 3;5 , Gm 1;21 , Gm 1,2;21 , and Gm 1,17;5 , and the absence of haplotypes Gm 1;13,15,16 , Gm 1;5,6 , and Gm 1;5,6,24 which have been found in other Jewish peoples. It is suggested that Ashkenazic populations have lower frequencies of haplotype Gm 1,17;5 than non‐European Jewish popul…
Population structure of the Juang tribe in Orissa, India
The coefficient of kinship of the Juangs, a very primitive tribe in the state of Orissa in eastern India, is estimated. The Juang population is sub-divided into two breeding groups: one practising shifting cultivation in the hilly regions of the former state Keonjher and Pal-Lahara, called here "primitive group"; the other settled in Dhenkanal and practising normal Indian agriculture, called here "advanced group". From the migration matrix the me…
