Consanguineous marriages were, and continue to be, a common practice among Indian families. Marriage partners were decided soon after the birth of the children. The families and the children were all mentally conditioned and nobody cared to think otherwise and the few who dared were ostracized. The offspring of such incestuous marriages were usually born with birth defects. Gradually over the decades, with education and exposure this practice has largely disappeared among the enlightened sections. But the bulk of our population still practices it due to sheer ignorance.
