The focus of this book is on the study of genes. Simply speaking, a gene is a section of a threadlike double helical molecule called deoxyribonucleic acid, abbreviated DNA. Genetics occupies a pivotal position in the entire subject of biology. Therefore, for any serious student of plant, animal, or microbial life, an understanding of genetics is essential. Genetics, like no other scientific discipline, is central to numerous aspects of human affairs. The gene, the basic functional unit of heredity, is the focal point of the discipline of modern genetics. In this book, effort has been made to analyse the patterns in which phenotypes are inherited in plants and animals. Major areas of study in this book are: Genetics and the Organism; Patterns of Inheritance; Chromosomal Basis of Heredity; and Gene Interaction
