Anthroposcopic Variation among Sub Tribes of Mali from Andhra Pradesh
The present paper reports the distribution of twelve anthroposcopic characters among two sub tribes of Mali viz., Manzai Mali and Bod Mali. Majority of Mali people are dark brown coloured and possess straight eye slits, straight nasal breadth and horizontal nasal septum. The forehead among majority of Malis is straight with medium height and breadth. Usually, the lips are medium sized and the prominence of chin is medium to receding. Dimple is se…
Multiple origins of the mtDNA 9-bp deletion in populations of South India
The origins and genetic affinities of the more than 500 tribal populations living in South Asia are widely disputed. This may reflect differential contributions that continental populations have made to tribal groups in South Asia. We assayed for the presence of the intergenic COII/tRNALys 9-bp deletion in human mtDNA in 646 individuals from 12 caste and 14 tribal populations of South India and compared them to individuals from Africa, Europe, an…

Genetic variability of blood and saliva antigens and serum proteins among subtribes of Mali from Andhra Pradesh, India
The subtribes of Mali viz. Manzai Mali and Bod Mali of Andhra Pradesh, India, were screened for A1A2B0, Rhesus (CcDEe) and MN blood groups, ABH saliva secretion and plasma proteins, namely haptoglobin, transferrin, caeruloplasmin and albumin. The genetic differences between the two subtribes are marginal and not significant except for ABH saliva secretion and plasma haptoglobin. Our observations suggest that the isolation of these two subtribes c…
Asymmetry and Correlations of Palmar Ridge Counts
Bilateral ridge count asymmetry and correlations among three palmar configurational areas. viz a-b-c and c-d in Manne Dora tribe from Andhra Pradesh are investigated. The highest mean directional asymmetry (MDA) for ridge count is noticed in c-d among men and a-b among women. The interdigital area c-d registers the highest mean absolute asymmetry (MAA). The correlation coefficients between ridge counts of various configrational areas indicate tha…
Genetic Diversity of PTC Taste Sensitivity Among Tribal and Caste Populations of Andhra Pradesh, India
The present paper reports the variability of PTC taste sensitivity among eight endogamous tribal populations inhabiting the Eastern Ghats of North Coastal Andhra Pradesh.

The tribal and caste groups present a relatively high genetic diversity, of which a major proportion is due to genetic differences within populations rather …
Inbreeding effects on reproductive outcome among seven tribes of Andhra Pradesh, India
The effects of inbreeding on reproductive outcome in terms of fertility and mortality were analyzed in seven tribal populations from Andhra Pradesh, India. The effect on mortality at both prenatal and prereproductive postnatal stages was further verified after estimating genetic load by an exponential regression model. Relatively higher fertility and mortality rates were recorded among consanguineous marriages than nonconsanguineous unions in the…

The estimates of opportunity for natural selection are reported for four endogamuus Andhra castes, namely. Chakali (0.6274). Kummari (0.9572). Mangali (0.6792) and Madiga (0.6957) The contribution of fertility to the total index is greater than the contribution of mortality among four populations studied. The average estimate of opportunity for natural selection recorded for the four Andhra castes (0.7399) is slightly higher than the average inde…
Individual fertility rate among minor tribal populations from Andhra Pradesh, India
The Individual Fertility Rate (IFR), a measure of current fertility status in small and illiterate preindustrial societies, is estimated for five tribal populations from Andhra Pradesh, India. The Andhra tribes exhibit high individual fertility rates ranging between 49.62 +/- 1.76 (Konda Dora) and 66.63 +/- 3.16 (Manzai Mali) and fall in the high-fertility category. The differences in IFR values between affinal and consanguineous couples are not …
Genetic load among four Andhra caste populations
The effect of inbreeding on mortality is assessed through genetic load estimates among four caste populations, the Chakali, Kummari, Mangali, and Madiga of Andhra Pradesh, India. The regression coefficient "B" is positive and statistically not significant except in the Mangali where reduced fetal wastage with increased inbreeding coefficient is noted. The B/A values of the majority of populations suggest that the genetic load is mainly segregatio…

The Madiga. a Scheduled Cane registers the highest frequency of group B (41%) followed by other three castes recording relatively higher frequencies of group B that group A. The Brahmin caste and Koya Dora tribe exhibit higher incidence of group A compared to group B. All the caste populations recorded…

The subtyping of group A reveals that group A2 records an incidence ranging from 0.98% to …
Genetic serum protein markers in eight South Indian caste and tribal populations
A total of n = 769 unrelated male and female individuals from eight endogamous caste (Brahmin, Kapu, Yadava, Relli) and tribal (Bagatha, Kotia, Manne Dora, Konda Dora) populations living in various districts of Andhra Pradesh (India) have been typed for haptoglobin (HP) types and transferrin (TF), group specific component (GC) and alpha 1-antitrypsin (PI) subtypes. The genetic heterogeneity among these population groups is considerable. This can …
