Description: Opens with a comparison of riding horses with work horses. Diagrams then define heredity and environment. Shows how cows may be bred for a particular hereditary quality, and how they are cared for in a favorable environment. Lists three general points: offspring tend to resemble their parents, offspring vary, and offspring tend toward the average. Illustrates these points with scenes of kittens and pigeons; then shows how Hank, the farm boy, also conforms to them. Pictures Hank as he might have been with the same heredity but different environment. As Hank is shown repairing a fence, studying, and engaged in other activities, the commentator points out that to improve one's surroundings is to influence one's environment., Mitosis and meiosis are shown to be the keys to human biology and DNA is described as the genetic code which provides the genetic range within which specific phenotypes may occur. Among the environmental forces which can affect this early genetic engineering are the nutrition of the mother-to-be, her emotions, physical health and psychological well-being. After the baby is born, mental development will be influenced by the type of home and school environment provided. Dr. Nevitt Sanford of the Wright Institute discusses the dignity of humanity and the self-respect which comes as a result of controlling one's own destiny as opposed to social or genetic definitions of self.
