The science of heredity and variation in living organisms is called?

The science of heredity and variation in living organisms is known as genetics. This field focuses on understanding how traits are passed down from one generation to the next through genes. Genetics examines the molecular structure and function of genes, the mechanisms of genetic inheritance, and variations in traits among individuals within a species. It provides insights into how organisms develop and how certain characteristics can be influenced by both genetic and environmental factors.

Biology, while closely related to genetics, is a broader field that encompasses the study of all living organisms, their structures, functions, growth, and interactions. Ecology, on the other hand, specifically studies the relationships between organisms and their environment, rather than heredity. Evolution deals with the processes that lead to the development of new species and changes in populations over time but does not directly define the mechanisms of heredity and variation, which is the core focus of genetics. Thus, genetics accurately encapsulates the study of heredity and variation in living organisms.
