Description
Black vestigial brown (b1vg1bw1) Carolina® Easy Fly® Drosophila culture of virgin female flies that demonstrate 3 autosomal recessive mutations. The black mutation causes black colorization on body, tarsi, and wing veins that darkens with age. The vestigial mutation causes reduced wings and halteres. The brown mutation causes pale red-brown eyes that darken with age.
The Easy Fly® system produces male-free cultures 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 larvae are exposed to high temperatures. Since only males have a Y* chromosome with this gene, female larvae are unaffected. Carolina performs the heat shock treatment in our laboratories, making your cultures ready to use upon arrival. For a complete guide on maintaining and studying Drosophila, including how to culture, anesthetize, and score them, and the genetic notations, consider our Carolina® Drosophila Manual (item #452620).
Note: Please order at least 2 weeks in advance of desired ship date. When culture arrives, remove caps but leave plugs in place. Keep cultures out of sunlight and maintain at 68–77° F (20–25° C).
