Quantitative Traits and Quantitative Genetics
2014In contrast with qualitative or dichotomous traits, quantitative traits are measured using quantitative or semi-quantitative variables and their inheritance is controlled by multiple genes acting independently or in association. Quantitative traits are also influenced to varying degrees by the environment and this explains why they are often designated

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: A critique
Social Biology, 1979Abstract The quantitative aspects of human genetics have hitherto been confined to (1) Mendelian categorization of qualities, which is enumerative and best applied to single‐locus conditions; and (2) Galtonian analysis, which is an examination of the first and second moments of quantities and best applied to multiple‐locus conditions.

AbstractIn this chapter the authors consider the theoretical basis of inheritance and possible sources of phenotypic variation and familial resemblance. The investigation of the genetic basis of psychiatric disorders first requires us to examine to what extent genes and environment contribute to a given disorder or trait.

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).

Quantitative Genetics and Mouse Behavior
Annual Review of Neuroscience, 2001▪ Abstract Quantitative differences are observed for most complex behavioral and pharmacological traits within any population. Both environmental and genetic influences regulate such individual differences. The mouse has proven to be a superb model in which to investigate the genetic basis for quantitative differences in complex behaviors. Genetically

The Genetic Architecture of Quantitative Traits
Annual Review of Genetics, 2001▪ Abstract Phenotypic variation for quantitative traits results from the segregation of alleles at multiple quantitative trait loci (QTL) with effects that are sensitive to the genetic, sexual, and external environments. Major challenges for biology in the post-genome era are to map the molecular polymorphisms responsible for variation in medically ...
