Molecular Genetics and the Human Personality
The DNA in your genes, for instance, is about These common genetic structures lead members of the same species to be born with a variety of behaviors that come naturally to them and that define the characteristics of the species. These abilities and characteristics are known as instincts— c o m pl e x inborn patt e rns of b e ha v iors that h e lp e nsure sur v i v al and r e pro d u c tion Tinbergen, Birds naturally build nests, dogs are naturally loyal to their human caretakers, and humans instinctively learn to walk and to speak and understand language.
But the strength of different traits and behaviors also varies within species. Rabbits are naturally fearful, but some are more fearful than others; some dogs are more loyal than others to their caretakers; and some humans learn to speak and write better than others do. These differences are determined in part by the small amount in humans, the 0. Personality is not determined by any single gene, but rather by the actions of many genes working together. Furthermore, even working together, genes are not so powerful that they can control or create our personality.
Some genes tend to increase a given characteristic and others work to decrease that same characteristic—the complex relationship among the various genes, as well as a variety of random factors, produces the final outcome. Furthermore, genetic factors always work with environmental factors to create personality. For example, a person may have a genetic variant that is known to increase his or her r isk for developing emphysema from smoking.
But if that person never smokes, then emphysema most likely will not develop. Choose a delete action Empty this page Remove this page and its subpages. Content is out of sync.

The author helps to undo a minor criticism I have with the title of this worthy book, which, in my mind, unintentionally tends to minimize its importance and scope. The next several chapters, all well written, seem to criss-cross through important and interesting topics in a somewhat puzzling order.
The chapter on autistic phenotypes is followed by a chapter on animal models of personality, which precedes chapters that weave through the genetics of particular loci, transporter systems, and the potential roles of serotonin and dopamine in human behavior from normal to pathological. The final third of the book is the most interesting from my point of view, with chapters on genetic aspects of cognition, aggression, and childhood temperament. All of these chapters are well written and enlightening and discuss particular behaviors as well as genetic underpinnings.
Wisely, the last few chapters of the book are devoted to dissenting opinions and discussion of the social implications of the ideas presented in the earlier chapters. The editors recognize that some of these ideas are not without controversy regarding the degree to which they have been accepted as well as their potential effects on society. Molecular Genetics and the Human Personality is a well-written and generally well-edited book that will be of interest to clinicians in several disciplines—primarily genetics, psychology, and psychiatry.
