A major in Biology consists of nine courses: Biology 110, 220, 230, 305, and five electives. Three of these electives must be taken at Franklin & Marshall. Four of these electives must have laboratory components. Required related courses are Chemistry 111, 112, and 211; Physics 111; and Mathematics 109 and Biology 210 (with permission, Psychology 230 or both Mathematics 221 and 322 may be substituted for Biology 210).
Biology 110, 220, and sometimes 230 are prerequisites to most higher-numbered courses. Most courses above Biology 230 require permission of the instructor.
The writing requirement in the Biology major is met by completion of one elective with a writing component. Regular courses satisfying the writing requirement in the Biology major are Biology 250, 306, 308, 309, 323, 324, 325, 326, 330, 332, 335, 336, 340, 341, 342, 345, 390, and 490. Some topics courses from 370–379 also fulfill the writing requirement in the Biology major. (BWR designates courses fulfilling the Biology writing requirement.)
A major in Biochemistry and Molecular Biology includes five biology courses (Biology 110, 220, 230, 305, and 334), six chemistry courses (Chemistry 111, 112, 211, 212, 321, and 375), and two electives from Biology and/or Chemistry. The electives must be chosen from the following list of courses: Biological Foundations of Behavior 490; Biology 240, 306, 307, 308, 309, 322, 324, 326, 332, some topics courses from 370–379, 390, and 490; or Chemistry 221, 222, 322, 384, 390, and 490. Only one semester of an independent study course (390 or 490) can count as an elective, and none of the electives can be a course without a laboratory. Required related courses are Physics 111 and Mathematics 109 and 110. Biochemistry and Molecular Biology majors may not declare a minor in Chemistry.
The Biological Foundations of Behavior major offers concentrations in Neuroscience and Animal Behavior.
Majors in the Department of Biology have studied abroad or off-campus in the following programs in recent years: Arcadia University Programs, University of London, University College, London, England and Guadalajara, Mexico; Butler University Programs, Australian National University, Canberra, University of New South Wales, Sydney, Australia, and University of Queensland, Brisbane, Australia; School for Field Studies, Baja, Mexico and Nairobi, Kenya; SEA Semester, Woods Hole, Massachusetts; School for International Training, Quito, Ecuador and Zanzibar, Tanzania; TASSEP (Trans Atlantic Science Student Exchange Program), University of Strathclyde, Glasgow, Scotland; The National Institute of Health Study Group, Colgate University, Bethesda, Maryland.
