Why do we study random chance and probability at the beginning of a unit on genetics? Genetics is the study of inheritance, but it is also a study of probability. In short, the genes that an individual organism inherits depends on the "luck of the draw," and the luck of the draw is dependent on the laws of probability. This lab demonstrates the Chi-square analysis as well as the concepts of random chance and the laws of probability through a coin toss exercise. It is an excellent exercise to prepare students for any genetics study including Drosophila breeding, especially Virtual Fly.
