Quizplus · Accepted Answer

Research in psychology suggests that the personalities of biologically unrelated children who grow up in the same home (such as adopted siblings) show little resemblance to each other, indicating that shared environment has a limited impact on personality development. Similarly, even biologically related nontwin siblings, who share a home environment and approximately 50% of their genes, also show only a little resemblance in personality. This suggests that both genetic factors and unique (non-shared) environmental factors play significant roles in shaping personality, rather than the shared home environment.
