Genetics and Evolutionary Change

This 22-lesson unit explores the molecular basis of inheritance, genetic technologies, and the processes that drive evolutionary change over time. You will investigate DNA structure, patterns of inheritance, natural selection, and the evidence that supports the theory of evolution.
