Nature vs. Nurture / Genetics vs. Environment

Highlights from December 11, 2009 Creating a Family radio show

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 us as parents through adoption or donor egg or sperm? Our guests were: • Dr. Matt McGue, Professor of Psychology at University of Minnesota, a behavioral and quantitative geneticist, and Co-Director of Minnesota Twin Family Study and the Sibling Interaction and Behavior Study and Research on Adoption. He is also an adoptive dad. • Dr. Nancy Segal, Professor of Psychology and 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. • Dr. Jenae Neiderhiser, a professor of psychology at Penn State University and Director of several long term twin and adoption studies that look at the interplay between genetics and environment.

  • There are different types of twin research designed to tease out the relative influences of genetics and environment.
  • In general, the research shows an interesting mix between nature and nurture on how our kids “turn out”.
  • Intelligence is impacted by both genes and environment. Adopted kids are usually more similar in academic achievement when living within the adopted family, but this environmental influence wanes as they age.
  • Personality and temperament are highly influenced by genetics. Again, more so as the child ages. But there are some surprising areas or temperament or personality that are more influenced by the environment.
  • Our guests evaluated the heritability of different types of mental illness, including bipolar, depression, schizophrenia, aggression, and alcoholism. We discussed the difference between being highly heritable and the odds of having the disease. We talked about this in the context of prospective adoptive parents evaluating an adoption referral or a potential birth mother match.
  • We talked about epigenetics as it relates to donor egg, donor sperm or embryo donation (embryo adoption).
  • ADHD and autism have a “moderate” genetic connection.
  • Obesity is highly influenced by genes.
