Purpose: The purpose of this lab is to simulate basic principles of genetic inheritance by designing and performing crosses with the fruit fly, Drosophila melanogaster.
•In this experiment, you will use the FlyLab to determine if a characteristic of Drosophila melanogaster is dominant or recessive to the wild-type phenotype.
•Review the video tutorials in the Week 3 Lecture on Single Trait Crosses, Two Trait Crosses, and Independent Assortment.
•Please contact me if you have any questions.
