How Genes Influence Behavior Jonathan Flint, Ralph J. Greenspan, Kenneth S. Kendler

Environment Recent evidence (Harris, 2006) suggests that the complex web of social relationships students experience—with peers, adults in the school, and family members—exerts a much greater influence on their behavior than researchers had previously assumed. May 16, 2014 - In addition, the relatively new field of epigenetics—the study of heritable changes in gene function that occur without a change in primary DNA sequence—blurs the line between nature and nurture. He produces no evidence for these behavioral genetics influences, however. May 16, 2014 - Wade believes this was due to the genes of the rich. Cats and other animals don't have a gene for friendliness or other complex behaviors. He simply asserts them, a bad move for a science writer. In cases where genes affect our behaviour, the same stretch of DNA can lead to very different deeds, depending on individual circumstances. Aug 16, 2010 - The same is true of our genes and our environments. Sep 17, 2013 - Variants in two adjacent genes, EGLN2 and CYP2A6, influence smoking behavior related to disease risk via different mechanisms. Behaviors themselves are not inherited. May 14, 2014 - It's worth noting at the outset that at no point does Wade downplay the effects of culture and environment in dictating social, cognitive or behavioral differences – in fact he mentions culture as an important factor at least ten times by my count – but all he is saying Wade brings a similar approach to exploring genetic influences on cognitive abilities and personality traits; evidently, as he recognizes, the evidence on this topic is just emerging and therefore not definitive. Jul 8, 2010 - Answering the question of how the genetic contributions from mom or dad affect an offspring's behavior just got a lot more complicated. Nov 10, 2008 - In most cases, we don't know how genes operate to influence behavior.
