Biology majors are provided the opportunity to concentrate in one of three sub-specialties: molecular and cellular biology, anatomy and physiology, or evolutionary and ecological biology. To prepare for an emphasis in one of these concentrations, all students are required to complete a core of basic biology courses. These two core courses are General Biology (101 and 102, two semesters) and Genetics (200). General Biology (101 and 102) is a prerequisite for Genetics. After completing the core courses, students are also required to take two core elective courses (one from any two of the concentration areas: molecular and cellular, anatomical and physiological, or evolutionary and ecological biology) and a minimum of 14 credit hours of advanced elective courses. Senior Seminar (493 or 494) is required of all majors, and is taken in the senior year. A student must earn a minimum of thirty-five (35) credit hours in Biology to fulfill the requirements for the major.
