Description:  This course surveys population genetics theory as applied to micro-evolutionary change in human populations.  We will look at the effects of mutation, selection, mating patterns, recombination, and genetic drift on changes in the genetic composition of human populations.  Initial emphasis is on mathematical analyses of these relationships at the micro-level.  We will then use this knowledge to examine applications of population genetics theory to human population history and evolution.

 

Objectives: The objectives of this course are to

(1) provide you with a solid foundation for understanding the genetic basis of evolution

(2) provide sufficient historical, intellectual, and mathematical background so that you can evaluate contemporary research in anthropological genetics.

(3) provide you with tools, concepts, and ways of thinking about quantitative problems in biological anthropology and evolutionary biology;

 

Textbook and readings: The text for this course is Hartl and Clark, Principles of Population Genetics, 3rd edition, published by Sinauer Associates.  Copies are available at the University Bookstore.  Be certain you get the third edition of this book as it differs substantially from previous editions.  There is also a copy on reserve at Odegaard.

The textbook is oriented toward general population genetics rather than human population genetics. Additional readings on topics of interest to anthropologists will supplement the text.  These will be made available on electronic reserve.

 


Course assignments:  There will be six problem sets during the course, one midterm exam, and one final exam.

 

Problem sets:  Each problem set will be handed out during lecture and will be due one week later.  Problem sets will include mostly quantitative problems with some short written answers. They may be worked on collectively, since collective problem solving (if done properly) can lead to some of the deepest learning.  If you work in a group, please indicate your work partner(s) on your paper.  Each of you must hand in a separate answer set, on which you will be graded separately.  Please do not work in groups larger than three or four.  You may use any books or notes you wish.  During some weeks we will leave time at the end of lecture on Friday to work on the problem sets.

 

Midterm and Exam:  The midterm will cover the first half of the course.  The final exam will focus on all material since the midterm, although this material necessarily builds off of the foundation laid in the first half. Both exams will be similar in format to the problem sets, although longer.  Both will be closed book, although you will be allowed to take in a single 8.5x11” sheet of notes.

Course Policies:

 

Grading:         Problem sets 10% each x 6 =             60%

                        Midterm                                  20%

                        Final exam                              20%

 

Late assignments:  Grades for late problem sets will be reduce by 10% per day, including any fraction of a day late. For example, if you would have gotten a 95% on the problem set, you will receive 85.5% if one day late, 77% if two days late, etc.  I will not accept problem sets more than a week late.

 

Other Policies:  Use common sense, be respectful of each other and yourself, and follow the University’s Student Conduct Code (http://www.washington.edu/students/handbook/ conduct.html) and policies on Academic Honesty (http://depts.washington.edu/grading/issue1/ honesty.htm).
