BI 230  is a prerequisite for all BI courses numbered 300 and higher. BI 250  should be taken in the fall or spring of the sophomore year. All students must also complete BI 299 - Biology Seminar  in the spring semester of their second year in the major. To acquire the remaining credit hours for the major, students must take biology electives at the 300 level or above; at least four of these electives must be lab courses. One of the electives must be an organism-based course chosen from the following: BI 301 , BI 302 , BI 311 , or BI 438  (indicated with an asterisk below). All senior biology majors must complete BI 480 - Biology Capstone . In addition, all biology majors must take general chemistry (CH 105 -CH 106  or CH 107 ).
