This document discusses Drosophila melanogaster, the common fruit fly, and its use in genetic research. It describes how crossing a wild-type male fly with a female fly that has an ebony body color can be used to study inheritance of traits. Tables show phenotypes observed from offspring and the expected results, allowing researchers to determine patterns of inheritance.
