Abstract

The principle of segregation is a foundational concept taught in introductory biology and genetics courses. This lesson i an online learning environment designed to enhance the student’s ability to work with and apply the concept of segregation to a plant breeding context. This learning environment includes video clips which transport the learner to the wheat field to meet a plant breeder working with their segregating plants and meet a contemporary who applies a virtual Punnett square explanation to the variation observed in the breeder’s wheat plants. Additional media integrated into the lesson design create the opportunity to practice the application of these biology principles in plant breeding.
