DNA. Located on each chromosome, the marvelous alpha-helix of deoxyribonucleic acid is the basis of our inheritance.
It is a marvel of genetic engineering to consider the possibilities. To produce a human being, while preserving perfect individuality and the near infinite variety of possibilities for facial appearance, height, bone structure, hair color, eye color, fingerprints is just amazing to our finite mind. In this chapter, however, I wish to consider some of the inherited tendencies and birth defects that cause great stress to parents and influence so profoundly the subsequent generation. Behavior Problems A whole new science of medical investigation has developed studying the influence of drugs and birth trauma on behavior. Many terms have been coined to describe these disorders of childhood, among them minimal brain dysfunction and hyperactivity. It is known that birth trauma—a difficult delivery, the traumatic use of forceps, or other conditions which result in oxygen deprivation—may produce long-term effects on behavior. Maternal use of drugs such as tranquilizers, cocaine, LSD, marijuana, and particularly alcohol (also numerous other substances) can induce changes that affect a person’s learning ability for his lifetime. Many children of school age are unable to concentrate, sit still, or adhere to the discipline of a schoolroom.
