This book provides an introduction to the field of quantitative genetics, which explores the inheritance of variations in metric traits, such as height or weight, caused by many genes acting together, with the effects of individual genes being indistinguishable. The author presents a theoretical framework based on Mendelian principles for understanding the genetic basis of continuous variation, extending the classical ideas of genetics to address quantitative differences. The book discusses methods for estimating heritability, predicting the response to selection, and assessing the impact of inbreeding and crossbreeding on quantitative traits. It covers topics like dominance deviations, interaction deviations, genetic correlations, and the maintenance of genetic variation under natural selection, providing a comprehensive overview of the principles and applications of quantitative genetics. The book's insights help us understand the genetic architecture of complex traits and inform breeding strategies for improving economically important characteristics in plants and animals, making it valuable for researchers, students, and practitioners in genetics, animal and plant breeding, and evolutionary biology.
This book is fantastic so far. Falconer and Mackay offer lucid and concise descriptions of the equations describing genetic and phenotypic change (and fortunately for me include only essential derivations). There is a clear emphasis on application to evolutionary studies, which gets me excited for application to my work in the near future.
