Quantitative genetics

Quantitative genetics, is the study of continuous traits (such as height or weight) that do not have straightforward Mendelian inheritance because they result from the interaction of many different genes.

The field was founded, in evolutionary terms, by the originators of the modern synthesis, Ronald Fisher, Sewall Wright and J. B. S. Haldane, and aimed to predict the response to selection given data on the phenotype and relationships of individuals.

More recently quantitative genetics has come to include the analysis of quantitative trait loci. Traits that are under the influence of a large number of genes are known as quantitative traits, and their mapping to a location on the chromosome requires accurate phenotypic, pedigree and marker data from a large number of related individuals.

Quantitative genetic analysis is used to determine how heritable a trait is, and how will it respond to natural or artificial selection. This analysis also gives insight into how populations evolve.
