Quizplus · Accepted Answer

This means that factors such as upbringing, parenting style, and family dynamics may not have as much influence on personality traits as was previously believed. It is important to note that while shared family environment may not be a significant factor in personality development, individual experiences and non-genetic factors can still play a role.
