Quantitative genetics

Quantitative genetics, the field founded by the originators of the modern synthesis, Ronald Fisher, Sewall Wright and J. B. S. Haldane, aims to predict the response to selection given data on the phenotype and relationships of individuals. A more recent development of quantitative genetics is 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 genetics build on some of the same principles as population genetics.
