Carolina™ Easy Fly™ Drosophila Time Saver Error-free system Females same as normal stocks Drosophila melanogaster is a popular organism for laboratory exercises in genetics. However, a significant barrier to using Drosophila in teaching or research is the collection of virgins for controlled crosses. Procuring adequate numbers of virgins takes a great deal of time, even for skilled collectors. Carolina's Easy Fly™ system makes this task EASY for both beginners and those who have used Drosophila for years. The Easy Fly™ system works by selectively killing male larvae with a 2-hour heat shock treatment, leaving only virgin females alive. Easy Fly™ males contain a modified Y* chromosome with a gene that activates programmed cell death when the larvae are exposed to high temperature. Since only males have a Y* chromosome with this gene, female larvae are unaffected. Carolina performs the heat shock treatment in our laboratories, so all shipped cultures contain pupae or adult flies that will develop into virgin females only. Use Drosophila strains with the Easy Fly™ mutation as you would traditional strains. Virgin females collected through this system are genetically identical to virgins collected from normal stocks. Easy Fly™ virgins may be readily mated to males bearing a normal Y chromosome.

• Time Saver
• Error-free system
• Females same as normal stocks

Say goodbye to manually collecting virgin female flies. With this efficient kit your students learn the basics of sex-linked inheritance using Drosophila melanogaster, an important model organism for genetics and developmental biology research. The activity demonstrates sex-linked inheritance through red-eyed (wild type) and our Easy Fly™ white-eyed Drosophila. The Easy Fly™ white line produces only female virgins ready for use. Materials are sufficient for a class of 32 students working in groups of 4.
