LabBench Activity

Genetics of Organisms

by Theresa Knapp Holtzclaw


In this laboratory you will study the patterns by which physical characteristics are transmitted from generation to generation. By breeding fruit flies (Drosophila melanogaster) of unknown genetic composition and studying the traits and ratios seen in their offspring, you will determine whether a trait follows a monohybrid or dihybrid pattern of inheritance and whether it is sex-linked or autosomal. You will use statistical analysis to support your conclusions.
