Answer: The given statement is False.
Personality can be described as a set of characteristics of an individual that includes behavior, emotional patterns, and perceptions, which define the individual as a whole.
Presence of siblings ( brother or sister) greatly influence the personality of an individual as siblings are their immediate friends from childhood till their whole life, with whom they learn to share and compromise for various situations. Due to this, they develop traits like care, empathy, and generous. These traits are less likely to develop in children who do not have siblings.
Thus, given statement is false.
