Corn Breeding: Introduction to Concepts in Quantitative Genetics
This is the second in a series of lessons specifically designed to instruct individuals without any formal training in genetics or statistics about the science of corn breeding. Individuals with formal training in genetics or statistics but without any training in plant breeding also may benefit from taking these lessons.

Plant breeders often work with traits, such as grain yield, that are controlled by many genes and/or are affected greatly by the environment. Such traits are known as quantitative traits, and the study of the inheritance of these traits is known as quantitative genetics. Because many traits that are economically important are quantitatively inherited, understanding quantitative genetics is important to plant breeders. In this lesson, some key concepts in quantitative genetics will be introduced, and these will give you some insight into the apparent paradox presented above.
