How much of our children’s personality traits, temperament, talents, health conditions, mental illness, and intelligence are controlled by their genes and how much by the environment we have created? What relevance does this have to adoptive parents?  In this course, Dr. Matt McGue, a behavioral and quantitative geneticist and co-director of the Minnesota Twin Family Study and the Sibling Interaction and Behavior Study and Research on Adoption; and Dr. Nancy Segal, director of the Twin Studies Center at California State University, Fullerton and author of Indivisible by Two: Lives of Extraordinary Twins and Entwined Lives: Twins and What They Tell Us About Human Behavior, discuss which traits are controlled by genetics and which by environment, and how that affects adopted families.
