Final answer:
The personalities of adopted children are often more similar to their adoptive parents than to their biological parents due to the influence of parenting styles on a child's temperament.
Step-by-step explanation:
The personalities of adopted children are often more similar to the personalities of their caregiving adoptive parents than to the personalities of their biological parents. This is because parenting styles can influence a child's temperament, and children with different temperaments may elicit different parenting behaviors. For example, easy children who are adaptable and social may evoke warm and responsive parenting, while difficult children who are demanding and irritable may evoke irritation in their parents.
