AbstractMost phenotypic traits are the product of many genes as well as environmental effects, and the resulting phenotypic variation is quantitative rather than qualitative. The extent to which traits are under genetic control is termed heritability, and can be estimated by analyzing the phenotypic similarity of related individuals.

Quantitative genetics is the study of continuously varying traits which make up the majority of biological attributes of evolutionary and commercial interest. This book provides a much-needed up-to-date, in-depth yet accessible text for the field. In lucid language, the author guides readers through the main concepts of population and quantitative ...

This chapter focuses on quantitative genetics, which analyses the inheritance of complex traits. Complex traits are multifactorial: their expression is influenced by multiple genes and various environmental factors. Most complex traits exhibit continuous phenotypic variation and threshold traits exhibit just two phenotypes.

QUANTITATIVE GENETICS IN PSYCHOLOGY
British Journal of Mathematical and Statistical Psychology, 1971The following paper proposes a simple theoretical model, capable of progressive expansion, to serve as a basis for the statistical investigation of mental inheritance. Formulae are deduced for the analysis of phenotypic variances, and for estimating the covariances and correlations between relatives of different degrees of kinship.

Abstract Quantitative genetics has traditionally been based on investigations of continuous or ‘metric’ phenotypes, where there are measurable differences between individuals, rather than on phenotypes that are simply present or absent (Falconer and Mackay 1996).

Understanding quantitative genetic variation
Nature Reviews Genetics, 2002Until recently, it was impracticable to identify the genes that are responsible for variation in continuous traits, or to directly observe the effects of their different alleles. Now, the abundance of genetic markers has made it possible to identify quantitative trait loci (QTL)--the regions of a chromosome or, ideally, individual sequence variants ...
