<p>Most biological science majors (including genetics in this case) will be taking the same classes during their first two years at UCD. These courses include Math 17a,17b,17c or 21a/21b, chem 2a,2b,2c, organic chemistry series, physics series, and bio 2a,2b,2c. You most likely wont really get into specific courses about genetics (upper division major courses) until beginning of your 3rd year. One good thing about this system is that you can switch into almost any biological science majors during your first 2 years without any worries about what you need to take. If you want a specific list of what you need to take, you can take a look at this link -> [UC</a> Davis General Catalog | Molecular and Cellular Biology (MCB) Requirements](<a href=“http://registrar.ucdavis.edu/UCDWebCatalog/programs/MCB/MCBreqt.html]UC”>http://registrar.ucdavis.edu/UCDWebCatalog/programs/MCB/MCBreqt.html)</p>
