Opportunity for natural selection among three endogamous subpopulations of Andhra Pradesh

“…[17] When the present Arya Vysya population is compared with the Vysyas reported by Rao and Murthy (1984) [18] there is a decline in the total index I (Crow's index), with a decline in the mortality and increase in fertility components. This is in agreement with Sphuler's review (1962,1963,1976) [19][20][21] of world wide data and studies at the National and State levels (Crow 1958, [1] 1972, [3] Jacquard and Ward, 1976, [22] Hed 1984 [23] etc) which suggest that the effect of demographic transition on the opportunity for natural selection among the populations of industrialized nations are a marked reduction in the total index, a decline in selection due to pre reproductive mortality, an increase in the fertility index initially, followed by a gradual decline and increase in the relative contribution of fertility component to the total selection.…”

Contribution of social and cultural factors to the decline in consanguinity in south India

“…It is more prevalent in rural areas than in urban areas and less among bettereducated women than among less educated/illiterate women (Rao and Inbaraj, 1977;Rao, 1983;Rao and Murty, 1986;Rao and Busi, 1988;Richard, 1995). A negative association between age at marriage and consanguinity is reported in a few studies (Richard and Rao, 1994;Richard, 1995).…”
