Preface

Population genetics is a fascinating branch of biology that focuses on the analysis of distribution and changes in the allelic frequencies of populations. Since its inception as a science in 1966, population genetics has advanced significantly due to the development of new molecular techniques, mathematical-statistical models, new software, and genomic databases. Currently, several theoretical and applied studies use the innumerable tools of population genetics for various inferences, analyzing the genetic structure of organisms for a better understanding of the dynamics of

This relatively recent science has important applications for the management of populations (natural and domesticated) as well as for evolutionary studies of the various factors that affect gene frequencies over time and across the world.

This book presents relevant results from carefully selected and evaluated popula-

In the first chapter, the editors make a brief and objective presentation on population genetics, with an emphasis on the evolutionary processes that cause changes in

The second chapter deals with a study of the mapping of vigor genes in wine grapes as a quantitative (polygenic) inheritance, characteristics associated with the storage capacity of carbohydrates, and also the high metabolism and rapid development of

In the third chapter, the authors present a review addressing a series of genetic factors associated with the characteristics of interest for breeding one of the world's

The fourth chapter is about a study with AFLP markers applied to studies of populations of a fish species of commercial interest, with implications for adequate management of fish stocks, actions that aim to minimize inbreeding, and decrease
