Peer Review 1
This study investigated the influence of genetic factor and personality on leadership role occupancy among a sample of male twins. Identical twins (n = 238) who share 100% of their genetic background were compared with fraternal twins (n = 188) who are expected to share only 50% of their genetic background. Results indicated that 30% of the variance in leadership role occupancy could be accounted for by genetic factor, while non-shared (or non-common) environmental factor accounted for the remaining variance in leadership role occupancy. Genetic influences also contributed to personality variables known to be associated with leadership (i.e., social potency and achievement). Furthermore, the results indicated that the genetic influence on leadership role occupancy was associated with the genetic factors influencing the personality variables, but there was no definitive evidence whether these personality variables partially mediated the relationship between genetic factor and leadership. Results are discussed in terms of the implications for leader selection and training.

Peer Review 2
A sample of 646 male twins (331 monozygotic or identical, 315 dizygotic or fraternal) completed a survey indicating their leadership role occupancy in work settings. Data on these individuals were also available for personality and cognitive variables. As predicted, two personality variables (Social Potency and Achievement) and a cognitive variable (a vocabulary test) were significantly correlated with the leadership variable. Subsequently, univariate and multivariate genetic analyses showed that a substantial portion of this leadership variance was accounted for by genetic factors (39 percent) while non-shared (or non-common) environmental factors accounted for the remaining variance in this leadership variable. Genetic influences were shown for the personality and cognitive factors as well. Finally, results indicated that the genetic influences for the leadership factor were substantially associated with or common with the genetic factors influencing the personality factors, but not with the cognitive variable.
