Abstract:One of the many advantages of Drosophila melanogaster as a model organism is the relative ease with which gene deletions can be generated by imprecise excision of transposon insertions. Here, we describe a simple, fast, and efficient method of screening for single-gene excision events that is not biased by prior assumptions of the mutant phenotype. DNA sequence polymorphisms were used as co-dominant electrophoretic markers to identify candidate deletions in a single generation, and to delimit the breakpoints t… Show more
