Quantitative Traits and Genetic Inheritance

Biometrical genetics is the study of the inheritance of quantitative traits and identifying the genetic determinants for variations in these traits.

Mendel

The multiple-factor hypothesis is the idea that multiple factors contribute to the inheritance of quantitative traits.
