TLDR
Quantitative genetics refers to the study of inheritance of traits whose phenotypes show more or less continuous distributions.
Abstract
Quantitative genetics refers to the study of inheritance of traits whose phenotypes show more or less continuous distributions. There is no compelling reason for distinguishing among related terms such as ‘biometrical genetics’, ‘statistical genetics’, nor, in some cases, ‘population genetics’. All are concerned with the study of how genes affect important characteristics, how they interact with environmental factors, and how they can be manipulated to give improved plant or animal strains.

Molecular-marker-facilitated investigations of quantitative trait loci in maize : 4. Analysis based on genome saturation with isozyme and restriction fragment length polymorphism markers.

TL;DR: Many of the factors that affected plant height quantitatively in this investigation were found to map to regions also including known sites of major genes influencing plant height, suggesting that some of the identified QTLs may be allelic to known major genes affecting plant height.

Using genotype-by-environment interaction for crop cultivar development

TL;DR: The chapter discusses the causes of genotype-environment interaction and how to deal with it, stability statistics, and ways to exploit or minimize interaction.

Epistasis and Plant Breeding

TL;DR: This chapter contains sections titled Why Is There More Evidence for Epistasis from QTL Experiments than from Biometrical Studies?
Journal ArticleDOI

What proportion of declared QTL in plants are false

TL;DR: The false discovery rate (FDR) is the probability that a quantitative trait locus (QTL) is false, given that a QTL has been declared, in an F2 mapping population given different numbers of QTL, population sizes, and trait heritabilities.

Family selection in plant breeding

N. W. Simmonds
- 01 Jan 1996 - 
TL;DR: A critical review of practical principles of genetic variances between and within full-sib families is proposed and only the best few, judged against standards as having potential for superior segregates, should be exploited thoroughly.

Introduction to quantitative genetics

TL;DR: The genetic constitution of a population: Hardy-Weinberg equilibrium and changes in gene frequency: migration mutation, changes of variance, and heritability are studied.
Book

The Selfish Gene

TL;DR: In this paper, the authors take up the concepts of altruistic and selfish behaviour; the genetical definition of selfish interest; the evolution of aggressive behaviour; kinship theory; sex ratio theory; reciprocal altruism; deceit; and the natural selection of sex differences.

Stability Parameters for Comparing Varieties

S. A. Eberhart, +1 more
- 01 Jan 1966 - 
TL;DR: The model, Yij = μ1 + β1Ij + δij, defines stability parameters that may be used to describe the performance of a variety over a series of environments to see whether genetic differences could be detected.

One Degree of Freedom for Non-Additivity

John W. Tukey
- 01 Sep 1949 - 
TL;DR: The present writer is usually much more concerned with and worried about non-additivity, and until recently has suffered from the lack of a systematic way to seek it out, and then to measure it.
