ICSE Class 10 Answered
Genetics and the environment both influence personality. Studies of identical twins, who share 100% of their genes, and fraternal twins, who share 50% of their genes, have shown that identical twins are more similar in personality than fraternal twins. This suggests that genes account for about half of the variation in personality.
The environment, which includes factors such as family, experiences, and culture, also plays a role in personality. For example, a child who grows up in a loving and supportive environment is more likely to develop a positive personality than a child who grows up in a stressful or threatening environment.
While genes and the environment both influence personality, the exact way in which they interact is still being studied.
