Genetics

Genetics is the branch of biology concerned with the study of genes, genetic variation, and heredity in living organisms. It explains how traits and characteristics are passed from parents to offspring through DNA. Genetics is fundamental to understanding evolution, development, and many diseases. Key concepts include Mendelian inheritance, molecular genetics, and population genetics. The field has applications in medicine, agriculture, and biotechnology, enabling advances such as genetic engineering and genome sequencing.
