This book is a revised and expanded edition of the classic 1979 volume that originally appeared in Springer's Biomathematics series. The author remains one of the leading researchers in the field of theoretical population genetics, a subject of growing importance given the recent advances in molecular biology and DNA sequencing.

Klappentext

This is the first of a planned two-volume work discussing the mathematical aspects of population genetics with an emphasis on evolutionary theory. This volume draws heavily from the author's 1979 classic, but it has been revised and expanded to include recent topics which follow naturally from the treatment in the earlier edition, such as the theory of molecular population genetics.
