Genetics is the branch of biology that focuses on genes, heredity, and variation in living organisms. It studies how traits and characteristics are passed from one generation to the next through genetic material (DNA or RNA in some viruses). Genetics covers topics such as gene expression, mutation, genetic recombination, and the roles of genes in diseases and evolution.
