This is a new edition of a textbook introducing undergraduate and graduate students, as well as researchers from fields like human genetics, to the science of population genetics. Hartl (Harvard U.) and Clark (Cornell U.) strive for a balance between theory and empirical observation in chapters discussing genetic and phenotypic variation; organization of genetic variation; random genetic drift; mutation and the neutral theory; Darwinian selection; inbreeding, population subdivision, and migration; molecular population genetics; evolutionary quantitative genetics; population genomics; and human population genetics. In order to encourage students to think critically and analytically about real-world data, problems are included at the end of each chapter, answers to which are provided at the end of the volume.
