While research suggests that genetics play an important role in personality, it is also important to recognize that other factors do have an influence. In many cases, the environment influences the expression of genes. Personality tends to be fairly stable, but that doesn't mean it is etched in stone.To define gene–environment interaction, it is useful to review the concept of conditional independence, which stipulates that the relationship between two factors is the same across strata defined by a third factor.In the context of the effects of two risk factors, A and B, on disease risk, conditional independence implies that the effect of factor A on disease risk …Twin studies are a first look into the genetics of a trait and tell us that there are such things as “genes for sexual orientation” (I hate the phrase “gay gene”).
