Describe two different techniques researchers use to investigate the relationship between genes and personality
What will be an ideal response?
Answer: A good answer will include the following key points.
? One way to estimate the genetic involvement in personality is to conduct twin studies.
? In one type of twin study, the similarity between identical twins is compared to the similarity between fraternal twins. Because identical twins share more DNA than fraternal twins, but are otherwise similar, a higher correlation between identical twins indicates a genetic influence on personality.
? To further separate the influence of environment from genes, another type of twin study looks at identical twins who were reared apart from each other.
? A different technique is to identify different versions of the same gene and then compare the personalities of individuals who inherited one version of the gene to those who inherited a different version of the gene.
