The recent explosion of data from the human genome has made advances in the quantitative study of human genetic variation increasingly crucial. This is the first book focusing on the field of population genetics as it pertains to humans. It offers an introductory, yet rigorous, treatment of the subject while engaging readers with case studies, examples, and extensive graphical representations. Mathematics is kept to a minimum and separate chapters cover the latest analytic methodologies and ethical considerations. It is a valuable textbook for courses in human biology and population genetics.
