Haryana were assessed. A sample of 200 pairs of twins in the age groups of 3-6 years were shorted out
from already identified twins from five cultural zones. Personality traits were assessed with the helpof
Five Factor Personality Questionnaire (Cathy, 2011). Regarding personal profile of the respondents, the
results revealed that most of the twins were boys having one sibling and second ordinal position.
Majority of the twins were living in joint family with large family size. With regard to parental
education, highest percentage of twins were having their fathers educated above matriculation but were
farmers. Where as mothers were educated upto middle school that was the reason they were
homemakers. Result on the twins indicated that all the traits, namely, agreeableness, extraversion,
neuroroticism, conscientiousness and openness were found to make significant difference in personality
traits of twins on the basis of standard calculation. The heritability estimates shown a great role of
genes in framing the overall personality of monozygotic twins.The associations of personality traits
were significantly related to mother education, father education, and family income in Mewat zones.
