This concise introduction offers students and researchers an overview of the discipline that connects genetics and evolution. Addressing the theories behind population genetics and relevant empirical evidence, John Gillespie discusses genetic drift, natural selection, nonrandom mating, quantitative genetics, and the evolutionary advantage of sex. First published to wide acclaim in 1998, this brilliant primer has been updated to include new sections on molecular evolution, genetic drift, genetic load, the stationary distribution, and two-locus dynamics. This book is indispensable for students working in a laboratory setting or studying free-ranging populations.
First published in 1998, John Gillespie's brilliant primer Population Genetics: A Concise Guide has been updated with new topics that have emerged . Keeping the concise format that made the book such a popular success, new sections have been added on molecular evolution, genetic drift, the stationary distribution, two-locus dynamics, and the evolution of selfing in nonrandom mating. Writing with verve, Gillespie explains both the theories and empirical evidence. The result is an intriguing revelation of how genes can be quantified and explained at the level of population. Whether one works on Drosophila in a laboratory setting or studies free-ranging populations, you will find that this book is an indispensable addition to your library.
This work provides a unified theory that addresses the important problem of the origin and maintenance of genetic variation in natural populations. With modern molecular techniques, variation is found in all species, sometimes at astonishingly high levels. Yet, despite these observations, the forces that maintain variation within and between species have been difficult subjects of study. Because they act very weakly and operate over vast time scales, scientists must rely on indirect inferences and speculative mathematical models. However, despite these obstacles, many advances have been made. The author's research in molecular genetics, evolution, and bio-mathematics has enabled him to draw on this work, and present a coherent and valuable view of the field. The book is divided into three parts. The first consists of three chapters on protein evolution, DNA evolution, and molecular mechanisms. This section reviews the experimental observations on genetic variation. The second part gives a unified treatment of the mathematical theory of selection in a fluctuating environment. The final two chapters combine the earlier assessments in a treatment of the scientific status of two competing theories for the maintenance of genetic variation. Steeped in the enormous advances population genetics has made over the past 25 years, this book has proven highly popular among human geneticists, biologists, evolutionary theorists, and bio-mathematicians.
