Q. Effect of heredity and environment on the development of personality.
Ans.
What is Personality?
Personality can be defined as a dynamic and organized set of characteristics possessed by a person that uniquely influences his or her cognitions, motivations, and behaviors in various situations.
Some say that personality is inherited or hereditary. Some raised the idea that it is environment that shapes one’s personality.

Heredity is one of the major factors in the development of our personality. Hereditary factors were passed by our parents and ancestors to us. The individual’s talent and some other

They were also asked to note their academic achievements (Olson et al., 2001).
The results of the study showed that differences between attitudes of the participants were at least partially correlated to genetic factors. It also showed that attitudes related to self-reported perspectives or to activities were often correlated. For instance, the survey asked subjects to rate themselves on the trait of sociability. That trait was correlated with 5 out of 6 attitude factors subjects had toward sociability. Attitudes toward athleticism highly correlated with findings on self-reported athletic abilities.
The causal model was expressly supported in these findings, because athletic skill (the mediator), for example, seemed to be linked with attitudes toward athleticism. Of course, this model is not without its problems: one cannot assume that X is the cause of Y in every single situation. Case in point: attitudes toward leadership seemed to be related to high self-ratings of physical attractiveness, sociability, and aggressiveness. Because of these numerous factors, it is still not possible to always accurately assume direct, singular relations between genetic traits and attitudes (Olson et al., 2001).
Interestingly, non-shared environment experiences between pairs of twins seemed to be the strongest cause of attitude variances, overshadowing genetic predispositions as well as shared environment
