Quantitative Genetics, Heritability, and Variances
For a couple of days I've been thinking about the canon of animal breeding, the important works that every student should read. I'm not up to the task right now of assembling a list of key scientific papers, and I suspect that there's already a good list somewhere that I can use as a starting point, so I'm going to go for low-hanging fruit instead.
Introduction to Quantitative Genetics (4th Edition)
Quantitative genetics theory for non-inbred populations in linkage disequilibrium. Although linkage disequilibrium, epistasis and inbreeding are common phenomena in genetic systems that control quantitative traits, theory development and analysis are very complex, especially when they are considered together. The objective of this study is to offer additional quantitative genetics theory to define and analyze, in relation to non-inbred cross pollinating populations, components of genotypic variance, heritabilities and predicted gains, assuming linkage disequilibrium and absence of epistasis. The genotypic variance and its components, additive and due to dominance genetic variances, are invariant over the generations only in regard to completely linked genes and to those in equilibrium. When the population is structured in half-sib families, the additive variance in the parents' generation and the genotypic variance in the population can be estimated.

The fourth edition of this classic text continues to provide the basis for understanding genetic principles behind quantitative differences, and extends these concepts to the segregation of genes that cause genetic variation in quantitative traits. The authors explain key techniques and methods. Genetic Constitution of a Population.
The presence of heterosis has been observed in many species at both phenotypic and gene levels. Strangely, the genetic basis of heterosis was and still is largely unknown. In this study, we extended and simplified some formulas that we reported previously.
