Introduction to genetic analysis 11th edition by Anthony Griffiths et al. WH Freeman. Purchase at campus bookstore . At least 2 copies of the textbook will be on reserved (3 hour loan) in the Stauffer Library.  

Learning Objectives

The goals of Biology 205 is to make genetics understandable, demonstrate its relevance, and to improve students’ critical thinking skills. I don’t want students just memorizing concepts without understanding how experiments are done and why they are done that way. This is probably not your first exposure to genetics analysis, but there will be new concepts you haven't learned so I will provide the necessary background such that you can understand these concepts. The second half of the course will focus on the molecular mechanisms that explain genetic principles. Students are expected to read the assigned readings and are encouraged to ask questions in lectures.

Grading Method

In this course, some components will be graded using numerical percentage marks.  Other components will receive letter grades, which for purposes of calculating your course average will be translated into numerical equivalents using the Faculty of Arts and Science Letter Grade Input Scheme.

When letter grades are employed, the following scale will be employed for purposes of calculating your course average:

Arts & Science Letter Grade Input Scheme

Assignment mark Numerical value for calculation of final mark

A+ 93

A 87

A- 82

B+ 78

B 75

B- 72

C+ 68

C 65

C- 62

D+ 58

D 55

D- 52

F48 (F+) 48

F24 (F) 24

F0 (0) 0

Your course average will then be converted to a final letter grade according to Queen’s Official Grade Conversion Scale:

Academic Integrity and Queen’s Code of Conduct

Students are responsible for familiarizing themselves with the regulations concerning academic integrity and for ensuring that their assignments and conduct conform to the principles of academic integrity. Information is available in the Arts and Science Calendar (see Academic Regulation 1 -, on the Arts and Science website (see, and at Biology’s website ( and from the instructor of this course. Departures from academic integrity include plagiarism, use of unauthorized materials, facilitation, forgery and falsification, and are antithetical to the development of an academic community at Queen's. Given the seriousness of these matters, actions which contravene the regulations on academic integrity carry sanctions that can range from a warning or the loss of grades on an assignment to the failure of a course to a requirement to withdraw from the university.

Accommodation Policy, Exam Conflicts, and Other Conflicts

Students who feel they need accommodations for disabilities or extenuating circumstances, or have a conflict between exams or other commitments should consult the Biology Department’s website for details about how to proceed ( In general, the earlier a course coordinator is apprised of an extenuating circumstance, the more likely an accommodation can be made. Students are encouraged to be proactive in anticipating difficulties, when it is possible to do so.

Students may apply to write a make-up or deferred exam if they have an exam conflict as defined in the Academic Regulations of the Faculty (See Arts and Science Calendar Regulation 8 - In this case, the student should report to the Exams Office first to verify that there is a genuine exam conflict. Biology professors will not consider your situation to be a conflict unless it meets the criteria set out by the Faculty of Arts and Sciences.

Students may request a make-up or deferred exam if they have an exam conflict with off-campus travel associated with a field course (e.g BIOL-307/3.0 or 407/3.0) that is held during the fall or winter terms.

Accommodation of Disabilities

Queen's University is committed to achieving full accessibility for persons with disabilities. Part of this commitment includes arranging academic accommodations for students with disabilities to ensure they have an equitable opportunity to participate in all of their academic activities. If you are a student with a disability and think you may need accommodations, you are strongly encouraged to contact the Disability Services Office (DSO) and register as early as possible.
