Abstract: Research on “examine the socio-emotional bihaviour among monozygotic and dizygotic twins” was conducted during 2016 at UAS Dharwad. Youth self repot (YSR) of externalizing, internalizing and total behavior problems were obtained for a sample of 78 twins (32 monozygotic and 46 dizygotic twins) from the Hubli and Dharwad cities. Snow ball sampling method was used to select respondents with age ranged 10 to 24 years. Findings revealed that majority of twins and singletons were indicated normal level with regard to dimensions, for internalizing, externalizing and total behaviour problems. Majority of them were had normal behaviours problem. It may due to their inter-twin relationship. It was found that, that, no significant association and difference between monozygotic and dizygotic twins for internalizing, externalizing and total behaviour problems. Among monozygotic twins, twin two had higher behavior problems as compared to twin one in all the three dimensions of socio emotional behaviour problems. However, there was no significant difference observed. The same trend was observed among dizygotic twins. With regard to total behaviour problems, twin two had higher behaviour problems which may be due over dependency on twin one. Dependent twins were significantly more likely to report feelings of inferiority and there was also more likely to be submissive than co-twin in the twin dyad. Results also found that there was no significant association between gender and socio-emotional behaviour problems. However, the mean score was higher for females among twins (17.17) than males (13.85) and significant difference was observed.. Females had higher somatic problems than males. The mean score for externalizing problems of singleton males (23.93) was significantly higher than girls. Males reported more aggressive and rule breaking behavior than females.
