Excerpt from Eugenics
The principle of independent unit characters states that the qualities or characteristics of or ganisms are, or may be analyzed into, distinct units that are inherited independently. It fol lows that the characters of a parent or a particular relative are not inherited as a whole but each individual is a mosaic of characters that appear in a variety of relatives.

Excerpt from Eugenics: The Science of Human Improvement by Better Breeding
I propose briefly to consider what is the present state of our knowledge of the inheritance of various characteristics.
The limitations in the scope of this booklet must be made clear at the outset. As a biologist, not a physician, I shall not consider many acquired conditions which render unfit for marriage. Governments spend scores of thousands of dollars and establish rigid inspections to prevent the spread of the coitus disease of the horse but the Spirochete parasite that causes the corresponding disease in man and entails endless misery on hundreds of thousands of innocent children may be disseminated by anybody, and is being disseminated by scores of thousands of persons in this country, unchecked, under the protection of the "personal liberty" flag. Alas! that so little thought is had to the loss of liberty of the infected children.

Paperback. Etat : New. Print on Demand. This book delves into the science of heredity and its potential for improving human well-being through informed mating choices. The author explores the inheritance of various traits, both desirable and undesirable, using eye color and hair texture as accessible examples. Moving beyond aesthetics, the discussion extends to abnormalities and diseases, highlighting how the same principles of inheritance apply. The author emphasizes that specific diseases are not directly inherited, but rather a susceptibility or resistance to them. This concept is illustrated through various family pedigrees showcasing patterns of vulnerability to ailments like respiratory illnesses and nervous system conditions. While acknowledging the crucial role of environment in shaping individual outcomes, the author underscores the power of genetic predispositions. The book then outlines how this understanding can guide individuals in selecting partners who share a similar level of resistance to specific health concerns, thereby increasing the likelihood of healthy offspring. Ultimately, this book offers a fascinating glimpse into the complex interplay of heredity and environment, providing valuable insights that can empower individuals to make informed decisions about family planning and contribute to a healthier future generation.
