Synopsis
Understand how selection shapes living traits with clear, practical guidance.
This book explains how choosing parents and mating patterns change a population’s genetics, and how scientists predict those changes in measurable traits like means, variances, and covariances.
In accessible terms, it walks through the logic of selecting for a trait, the role of gene frequencies, and the difference between artificial and natural selection. It shows how to estimate heritability and use it to forecast responses, with concrete examples from experiments on fruit flies and other organisms. The discussion stays focused on observable results while keeping sight of the underlying genetic ideas.- How selection alters trait means across generations
- The relationship between selection differential and response
- How heritability connects parents, offspring, and predictions
- Practical methods to predict outcomes without tracking every gene

From the Back Cover
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.
