Abstract: Many topics of interest to developmental scientists are informed by behavioural genetic findings and their implications. First, behavioural genetic theory and methods will be briefly outlined. Next, findings will be illustrated by considering two disparate areas – general cognitive ability (IQ), and children's self-conceptions. These topics have yielded some surprising results that fundamentally change the way we think about the influence of families.
