Things like environment, routines, expectations of family members and friends, and diet are all part of nurture. Today, it is commonly accepted that most aspects of a child's development are a combination of both nurture and nature.

    Twins are often used to study the "nature vs. nurture" debate. Identical (or monozygotic) twins share the same genes, which makes them very appealing for scientists studying genetics or the "nature" side of the nature/nurture argument. Twins, including fraternal (dizygotic) twins who are raised in the same household are assumed to share the same environmental, familial and cultural influences. This addresses the "nurture" side of the argument.

    In most cases, a twin study follows twins which grow up in the same household. Ideally, the study should compare other ...
