Genes account for between approximately 50-60% variations in verbal abilities. Human genetic research aimed to characterize the genetic and environmental influence on verbal aspects namely information, vocabulary, similarities and comprehension of twins and correlation between monozygotic and dizygotic twins belonged to Bhiwani and Hisar district of Haryana State. Environmental influences were mainly of the non-shared variety, suggested that twins from the same family experience verbal differently. The result indicated that the correlation of monozygotic twins was more for information (0.79), vocabulary (0.74), similarities (0.61) and comprehension (0.62) in both districts namely, Bhiwani and Hisar. Twin study indicated that most verbal characteristics were heritable. Human genetic research also recognized the importance of environmental factors that also affect the verbal aspects of twins. The heritability estimates was used to assess the genetic influence on verbal abilities of twins. There was strong evidence that the heritability estimates of verbal abilities of twins ranges from 50 per cent to 60 per cent and the remaining 50 per cent to 40 per cent variance in verbal abilities of twins was accounted to environmental circumstances. Thus, the genetic pay more significant role in shaping the verbal abilities of twins.
