Genetics is the branch of biology that studies genes, heredity, and variation in living organisms. It explores how DNA encodes the instructions for life, influencing traits, evolution, and susceptibility to disease. From understanding the structure of the genome to mapping gene expression and editing with technologies like CRISPR, genetics underpins modern medicine, biotechnology, and evolutionary biology. Research in this field reveals how genetic mutations cause disorders, how genes interact with the environment, and how inherited information drives diversity across species. As sequencing and computational tools advance, genetics continues to transform our understanding of biology, health, and human identity.
