The lastest edition of this classic text continues to provide the basis for understanding the genetic principles behind quantitative differences in phenotypes and how they apply to animal and plant improvement and evolution. It extends these concepts to the segregation of genes that cause genetic variation in quantitative traits. Key techniques and methods are also covered.
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.
