The program of the Department of Biological Sciences is designed to contribute to a scientific background as part of a liberal education. The department offers a diversified, broadly based program, which can be designed to satisfy many areas of study. Our multitrack major can provide the traditional student with a well-rounded background in biology, or students may select courses to prepare them for a particular area of study. The multitrack curriculum can prepare students for graduate study, pre-health professional fields (such as medicine or dentistry), marine biology, or environmental science. The department has persons trained to advise in each of these areas. A list of advisors for a specific track or area of study can be obtained from the departmental office.

Students desiring to major in biology must meet the general requirements for the degree of Bachelor of Science in addition to the following requirements:


1. At least 37 semester hours of biology, including:

a. BLY 121, 121L, 122, 122L                                              (8 hours)


b. BLY 301, 302, 303                                                            (9 hours)

c. At least 20 hours of biology 300-400 electives.      (20 hours)

The upper-level choices will be based on career counseling provided by advisors using models of tracks including (but not limited to) Botany, Ecology and Evolution, Environmental Science, Marine Biology, Cell/Molecular Biology, and Zoology.   For examples follow this link


2. Chemistry 131, 132, and 201

3. A year of Physics (114, 115) or Geology (111 and 112).

4. Mathematics through Calculus (MA 115 and MA 125) or Statistics (MA 115 and ST 210)


Students must also complete two writing (W) courses.


Biology majors may minor in the Related Sciences Minor by taking CH 131, CH 132, and CH 201 and two of the courses from the following list:

    • CH 202, CH 265, CH 440, CH 441 or Ch 414 (Ch414 requires CH 265 as a prerequisite)
    • GY 344, GY 371, GY 413, GY 461, GY 111 or GY 112
    • MAS 573, MAS 575, or MAS 589


Areas I, II, and III of the General Education Requirements for Biology are specified in the university bulletin (College of Arts and Sciences section). Note that Area IV requirements (Mathematics and natural Sciences) are fulfilled by the major requirements specified above.



Twenty-five semester hours of biology are required, including:

  1. BLY 121, BLY 121L, BLY 122, BLY 122L,(General Biology) 
  2. BLY 301, BLY 302, and BLY303 [please note that CH131 is a prerequisite for these three classes]
  3. Four hours in upper level laboratory courses taken in the Biology department at the University of South Alabama.

Credit will not be allowed for both the non-major (BLY101, BLY101L and BLY102, BLY102L) and the major/minor sequence (BLY121, BLY121L and BLY122, BLY122L).
