Department of Biology

The Undergraduate Biology Program at SFASU

Biology Major

     Students wishing to choose a major in biology should consult the chair of the department early in their university career. Since the department includes a number of biological disciplines (zoology, botany, molecular, cellular, evolutionary biology, etc.), no single curriculum can be listed for all majors. Each student is strongly encouraged to work closely with a departmental adviser to design the program best suited to the interests and goals of the student.  

     Below are the course requirements for obtaining the degree of Bachelor of Science with a major in biology. A minimum of 40 semester hours of biology, including the core curriculum, (with 15 hours in advanced courses) is required for a B.S. degree with a major in biology. Biology majors must also satisfy all the requirements of the B.S. degree for the College of Science and Mathematics outlined here.

     While completing a common core of courses that is taken by all majors, students must also select from one of the following degree tracks: botany, cell and molecular biology, or ecology and evolutionary biology.

Biology Major Requirements: B.S. Degree (40 semester hours)

          Core Requirements
(22 hours)
          Life Science Core (19 hours): BIO 130, 131, 133, 341, 370, and 470

          Ecology (4 hours): BIO 313, 403, or 450

          Degree Tracks
(18 hours each)  
          A full list of required courses within each degree track is listed under Areas of Study

          ● Botany (17-19 hours)

          ● Cellular & Molecular Biology (16-20 hours)

          ● Ecology & Evolutionary Biology (14-22 hours)

     Each student is also required to complete a minor of 18 to 24 additional semester hours in a single discipline. At least six hours in the minor must be in advanced-level courses at SFA. Biology majors may choose combined-sciences major consisting of CHE 133, 134; eight hours from GOL 131, 132 or PHY 131, 132; plus six advanced hours from CHE, GOL or PHY. Biology majors contemplating graduate work are advised to elect a minor in a selected science or mathematics.

General Course Prerequisites

      A minimum grade of C is required in all courses that are prerequisites to a biology course. Students must be TSI complete or exempt or have completed all required developmental courses with Cs or better in order to enroll in BIO 130, 131, 133, 238, and 239.
