Introduction

Understanding the inheritance of a single trait which differs between two parents is the goal of a monohybrid cross experiment. In reality though, parents rarely differ by only a single trait so the next logical step in classical genetics would be a dihybrid cross experiment. The goal in this type of experiment is to understand how two traits that vary between parents are inherited. The experiment described in this lesson was a combined effort of Dr. Jim Specht and an undergraduate genetics class.
