This core second-year biology course examines patterns of inheritance, genes, and gene functioning from DNA to phenotype. Mendelian patterns of inheritance and exceptions will be discussed and expanded on from introductory material in first-year Biology (Biology 101 and 102). Current topics in molecular techniques, transmission, stem cells, and ethics will also be discussed. Lab exercises will focus on basic quantitative techniques of analysing genetic frequencies and basic methodology in conducting genetic experiments, as well as practise employing rigid scientific process.

Students must also register in the mandatory lab component of the course, BIOL 202L.

Prerequisites: BIOL 101 and BIOL 102, both with a minimum grade of C.
