Genetics studies how living organisms inherit many of the features of their ancestors —for example, children usually look and act like other people in their family. Genetics tries to identify which features are inherited, and work out the details of how these features are passed from generation to generation. In genetics, a feature of an organism is called a 'trait'. Some traits are features of an organism's physical appearance, for example, a person's eye-colour, height or weight. There are many other types of traits and these range from aspects of behaviour to resistance to disease.
This book is a complete introductory text containing divergent topics of genetics under one cover. The text material is arranged in eleven chapters with several examples and illustrations. Its readers will derive a rich understanding of the basic concepts of genetics.
