This selective review considers findings in genetic research that have shed light on how genes operate across development. We will address the question of whether the child is "father of the Man" from a genetic perspective. In other words, do the same genetic influences affect the same traits across development? Using a "taster menu" approach and…

The phenotypic and etiologic relation between internalizing and autistic-like traits is studied using a community-based twin sample. Internalizing and autistic-like traits showed moderate phenotypic overlap but have specific genetic influences.

Factor structure and relationship between core features of autism (social impairments, communication difficulties, and restricted, repetitive behaviours or interests (RRBIs)) were explored in 189 children from the Twins Early Development Study, diagnosed with autistic spectrum disorders (ASDs) using the Development and Wellbeing Assessment (DAWBA;…
