-mitosis and meiosis and chromosomes: it is important to understand the distinction between a double-stranded and single-stranded chromosome; and between a haploid state and a diploid state for a cell (and under what circumstances they occur);  it is unimportant to know the names of the phases of meiosis and mitosis.

Course requirements

The readings for this course will be taken mainly from a collection of papers that will be distributed by the professor.  Additional readings from other sources may sometimes be assigned.  Of course, students are encouraged to branch out and do more than the minimum required reading. Take responsibility for your own learning.  You will find the work much more rewarding if you come to class prepared, having read the assignment carefully so that you can participate in discussions.  Attendance is requiredDo not be late for class as it disrupts all of us.  Students will write two or three  essay problem sets, either in class or at home.  From time to time, I may give a brief quiz on the assigned reading at the beginning of a class.  Late papers will not be acceptedAll of the assigned work must be completed in order to pass this course.  If you must miss a class it is your responsibility to get the assignment and come to the next class prepared.  Please do not email me or leave phone messages for trivial matters (e.g. is it ok for me to be late...can you put the assignment in my box...etc.).   Please check my office hours (posted outside my office, Dickinson 108) or make an appointment with me at the end of class.  If you are having difficulty with the work, please come talk to me!

Class comportment and common decency
It is important for all of us to come together as a group interested in discussing problems in the biology of the sexes.  Each of us is part of this group, and as such, our behavior is not just about each of us as individuals, but also about being members of a group.  Be respectful and attentive.  Do not arrive late, as it is disrespectful and disruptive.  Do not leave the room during class, as it is disrespectful and disruptive.  Plan your time.  Use the bathroom before class.  Bring water, tissues, lozenges, etc. with you. Do not engage in any activity that you would avoid at a job interview (e.g. do not pick your nose or skin, do not slouch, play with your hair, chew on your nails, etc.)  Turn off your cell phone before coming to class.  Do not surf the web or check your email during class. 

Class attendance is required.  Plan your work. All assignments must be submitted on time in order to pass this class. Frequently I write assignments on the board or project them in class so be prepared to write them down. If you must miss a class, it is your responsibility to get the assignment and find out from another student about missed work. If you plan to miss class before or after Long Weekend or Thanksgiving, either change your plans or do not take this class.  If you plan to miss the last class, either change your plan, or do not take this class. An absence is an absence with no distinction between excused and not.

The work is the thing.
