Animal genetics is the study of how traits and characteristics are inherited in animals. It focuses on understanding the role of genes, which are segments of DNA that carry information. By examining these genes, scientists can learn how specific traits, such as coat color or disease resistance, are passed from one generation to the next. This field is important for various applications, including animal breeding and conservation biology. By using genetic information, breeders can select animals with desirable traits to improve livestock or pets. Additionally, understanding genetics helps in preserving endangered species by maintaining genetic diversity within populations.
