Almost any trait that can be defined shows variation, both within and between populations. Quantitative genetics is concerned with the analysis of the genetic and environmental basis of this variation. Classical genetics typically deals with single genes of large effect, while quantitative genetics often assumes a large number of genes, each with small effects, influence trait variation.
