Inbreeding among three endogamous groups in a multicaste village of Andhra Pradesh, India

Abstract The frequency of consanguineous marriages was studied in three endogamous castes, the Reddis (Kapus), Yadavas (Gollas), and Madigas of Marripadu village in South India. Inbreeding was higher among the Yadavas (Gollas) (0.0312) and Madigas (0.0271) than among the Reddis (Kapus) (0.0154) due to their higher frequencies of uncle‐niece marriages.

Morphometric Status of Human Skeletal Remains From Kodumanal, Periyar District, Tamil Nadu

Abstract This paper presents the morophological and metric descriptions of three human skeletons, two females and one male, recovered from a pit burial in the excavations at the megalithic-cum-early historic site of Kodumanal in the Perundurai taluk of Periyar district, Tamil nadu. Apart from the study of three crania, the post-cranial bones of the male individual have been subjected to a good number of measurements, a detailed analysis and discussion. The findings of the study have been comparatively evaluated with those reported earlier on the skeletal remains of the megalithic period, with a view to understanding the physical affinities of these people.

Qualitative Finger Dermatoglyphic Variation and Distance Among Four Reddi Populations of Andhra Pradesh

Abstract In a sample of 800 unrelated male individuals, 200 from each sub-castes of Desuri Reddis (DSR), Pedakanti Reddis (PKR), Motati Reddis (MTR) and Kodide Reddis (KDR) were studied to estimate variation and distance among and between the populations by using qualitative finger dermatoglyphic characters such as finger pattern types, symmetrical and assymetrical distributions and monomorphic hands. The highest (2.402054) and lowest (1.384128) B1 values are observed between the DSR-MTR and PKR-MTR groups, respectively. The cluster analysis dendogram and principal coordinate analysis depict clearly the heterogenous nature of the selected Reddi groups.

Anthropometric Variation among the Reddis of Southern Andhra Pradesh, India

Five select Reddi populations based on 750 males in the age range of 20 to 50 years have been studied for 15 anthropometric measurements and 10 indices. The Pokanati show higher mean value for a majority of the measurements. F-values are significant for all measurements except for bicristal breadth. All indices but nasal index show negligible variation. Mesocephalic heads predominate among Pokanati and dolicocephalic heads among the rest. the cluster analysis and principal coordinate analysis, as diagrammatically represented, show the extent of variation among the five Reddi populations.

Effects of parental consanguinity on some morphometric traits in the Brahmins of Andhra Pradesh

A sample of 158 persons (74 of consanguineous and 84 of nonconsanguineous marriages) was studied to evaluate the effects of consanguinity on selected morphometric traits. The study revealed that the mean weight is lower in related than in unrelated males while it is vice-versa in females. With respect to height and head measurements top consanguineous values are less than the unrelated ones though the differences between them are statistically insignificare.

Genetic Defects in Karnataka (India): Evidence and Factors

Abstract Five family pedigrees of people of Karnataka have been analysed to study the inheritance pattern of the genetic defects of missing left forearm, polydactyly, atrophied toes and nails and lobster claw deformity of hands and syndactylous feet, all possibly autosomal dominant genetic traits. These deformities affected eight persons among a total of 211 individuals represented by five pedigrees belonging to 18 generations. They are from Lingayat, Muslim, Valmiki and Brahmin communities inhabiting Dharwad city, Hosahalli Village in Dharwad district and Hubli city. The first pedigree siblings of the propositus with missing left forearm and the second and third pedigree siblings as well as the ancestors of the propositi with polydactylous hands were all phenotypically normal, indicating the variable expression of the gene for polydactyly. The fourth pedigree propositus with atrophied toes and nails might be attributed to a condition known as anonychia. The fifth pedigree proposita with cleft hands and syndactylous feet might have resulted due to autosomal dominant genes with variable expressivity and penetrance. The variable expression of genes for polydactyly and anonychia in the Karnataka females is predominantly a vertical type of inheritance rather than horizontal one. With the help of these pedigrees an attempt has been made to interpret the pattern of inheritance of the reported anomalies.

Serogenetic Variation Among the Dhobis of Tirupati, Andhra Pradesh

Abstract The present paper report the A1 A2 BO and Rh(D) blood groups variation among the two sub-castes of Dhobis namely Murikinati Dhobis(MND)and Reddibhumula Dhobis(RBD)in Tirupati town of Andhra Pradesh. The A1 A2 BO and Rh(D) blood groups reveal the homogeneous nature of the two groups with the highest proportion of ‘O’ group persons. The overall picture of ABO percentage in Murikinati Dhobis is O (49.63%) > A (29.85%) > B (16.04 %) > AB (4.48 %), whereas, in Reddibhumula Dhobis it is O (45.68%) > B (26.77%) > A (21.65%) > AB (5.90%). The values of AA: OO ratio is found to be more in Reddibhumula Dhobis (1:9.05 ) and the values of BB: BO ratio is higher in Murikinati Dhobis (1:12.97). The Rh -ve frequency was found to be more among Murik inati Dhobis (5.2%)than Reddibhumula Dhobis(4.3%).

Tongue Rolling and Tongue Folding Among Four Reddi Sub-Castes of Andhra Pradesh

Abstract The paper reports the variation of tongue rolling and folding among four sub-castes of the Reddis, a major caste population of Andhra Pradesh, based on a randomly selected sample of 800 unrelated male individuals, 200 from each sub-caste. The Proportion of tongue rollers was comparatively lower than non-rollers in Kodide Reddis(28.50%) followed by Pedakanti Reddis(44.50) and Motati Reddis(48.00%), whereas in Desuri Reddis(37.50%). In Comparison with other populations of Andhra Pradesh the Reddis showed a relatively lower frequency of tongue rollers and a higher frequency of tongue folders.

Micro-Evolutionary Dynamics in Reddis of Andhra Pradesh

Abstract An integrated approach of understanding micro-evolutionary dynamics of a population through Breeding size, effective size, migration and drift and opportunity of selection, iss considered in the present paper. The data for the present study have drawn on pregnancy outcome of 585 women from the four subgroups of larger Reddi population of Andhra Pradesh. The breeding size for the pooled population is lower (2061) than the effective size (2822). This is mainly due to smaller mean number of children (2.33) for the couples and lower values of variance (0.91). The selection intensity (1) in the pooled Reddi population is again lower. i.e., (0.4128) and selection is operating through index of fertility (0.2748). The demographic situation of Reddis for these chief aspects of micro-evolutionary dynamics of its population structure indicates that the Reddis appear to be modern and technologically developed population and proves to be the same even in ts comparison with consemporary populations.

Morphological Variation of Certain Traits Among The Scheduled Caste Madigas of Andhra Pradesh

The paper reports the morphological variation of earlobe types, cleft chin, and hypertrichosis of the ear and eye-brow types among the two Madiga groups, belonging to the same sub-caste of Gampadhompti Madigas: Madigas at Cuddapah District (MDCOP) and Madigas of Chittor District (MDCTR). The proportion of persons with attached earlobe is lower in MDCDP (26.22%) than in MDCTR (38.79%), with highly significant sex difference in the latter group. The overall incidence of the trait of attached earlobe of the pooled Madigas is relatively lower than in other population. The cleft chin incidence in pooled Madigas is highly variable in male series (27.85%) with highly significant sex and intergroup differences, and shows larger variation compared to other populations. Hypertrichosis of the ear is found to be lower in MDCDP (20.38%) than in MDCTR (23.53%), and the overall incidence of pooled Madigas is somewhat higher than in other populations. Continuous eye-brow type is less common in the pooled Madigas (16.56%) with negligible group difference and significant sex difference in either group.
