Title: simple mendelian genetics IN drosophila melanogaster Objectives:. To introduce normal "wild type" and various mutant phenotypes. Take a look at written paper - Lab Report : Drosophila melanogaster genotyping. It is to perform Drosophila melanogaster genotyping using the method Polymerase Chain Reaction (PCR).

Introduction: The, drosophila melanogaster, the common fruit fly, has been used in genetics since 1910 for primary research (Genetics Laboratory Manual). The ratio of wild type to sepia to vestigial and to sepia, vestigial.5:2.3:1.8:1 seen in the F2 is very near that of the expected 9:3:3:1 ratio for a dihybrid cross, and the Chi square test verifies that it is within statistical limits. After the third instar, larvae will begin to migrate up the culture vial in order to pupate.
