Populations with two or more variations of particular characteristics are called polymorphic. The distribution of phenotypes among individuals, known as the population variation, is influenced by a number of factors, including the population’s genetic structure and the environment.

It details concepts such as selection differential, the relationship between responses to selection and progeny phenotypes, and the use of equations for genetic gain and heritability estimation. Methods for estimating narrow-sense heritability using ANOVA and REML are discussed, along with the significance of family variance.

Microbiologists played significant roles in demonstrating that DNA is the hereditary information found within cells. In the 1850s and 1860s, Gregor Mendel experimented with true-breeding garden peas to demonstrate the heritability of specific observable traits. In 1869, Friedrich Miescher isolated and purified a compound rich in phosphorus from the nuclei of white blood cells; he named the compound nuclein.
