Quantitative genetics
Quantitative genetics is the study of the inheritance of traits that vary in degree and can be attributed to the combined effects of multiple Genes, using statistical methods to analyze and predict the inheritance of these traits. This field combines concepts from Mendelian genetics, Statistics, and Evolutionary biology to understand the complex relationships between genes, environment, and phenotype. Quantitative geneticists use tools such as Heritability estimates and Breeding values to predict the response to Selection (biology) and understand the evolution of complex traits. The work of quantitative geneticists has applications in fields such as Plant breeding, Animal breeding, and Pharmaceutical research. Key figures in the development of quantitative genetics include Ronald Fisher and Sewall Wright, who laid the foundation for the field with their work on Population genetics and Evolutionary theory.
