Genetics

This subcategory gathers theories belonging to genetics: the models describing how heredity works at the level of genes, chromosomes and molecules, including the mechanics of inheritance from Mendel onward, the molecular machinery connecting DNA to protein, and the population-genetic and molecular-evolutionary models built on that machinery. A theory placed here explains a hereditary or molecular-genetic mechanism, distinct from a theory concerned with the broader course of life's history and diversity, which stays in biology.
