Acquiring a scientific attitude toward human personality is not easy. There are all sorts of emotional and theoretical problems involved in the study of it. It involves treating another human being as if he were a thing—a tree or a stone —to be analyzed, rather than loved, hated, or judged. While it 's clear that physical characteristics are hereditary, the genetic waters get a bit murkier when it comes to an individual 's behavior, intelligence, and personality. Scientists do know that our DNA and life experiences play a major role in who we are, but how much of that is still under question.
Researchers study variation in behavior as it is affected by genes, this study is called behavioral genetics. Genes are the units of heredity passed down from parents to offspring (Berg 1983; Mclelland 1981). The initial difficulty that scientists face in describing personality by traits is that there are a myriad of traits in the human body. No single gene determines a particular behavior. Behaviors are complex traits involving multiple genes that are affected by a variety of other factors. This fact often gets overlooked in media reports hyping scientific breakthroughs on gene function, and unfortunately, this can be very misleading to the public (Paul 1998 et al., Catell 1980). At the same time, environments influence the actions of genes.
The human genome is organized into two sets of twenty-three chromosomes, forty-six in all. Each chromosome contains molecules called nucleotides.…
