Fly lab instructions

Be prepared to explain why this happens in your final lab report. These are black and very distinctive but can only be seen under relatively high magnification.

Allow media to warm to room temperature before adding flies. Publisher: Biologycorner. Allow the vial to sit for a few minutes, adding additional water if necessary until the media is completely hydrated.

B An alternative way is to put the flies in the freezer for about 8 minutes. They chose a mutant and crossed that fly type with wild type flies to observe the results. Small Group instruction Introduction This page describes our experience guiding groups of students through the dual process of conducting a basic genetics experiment with Drosophila melanogaster and documenting the project by creating Treehouse web pages. The least harmful to the flies is either carbon dioxide or cooling anesthetizing. Computer at least one per group for construction of treehouse web pages Prior Knowledge Before or during the fruit-fly raising process, students should be familiarized with basic genetics vocabulary and practice making a 1-trait punnett square. Be sure to select robust, healthy males; the older the flies, the lower the mating efficiency. When writing the genotype, in general, chromosomes are separated with a semicolon. Physical Materials and Tools Flies and supporting materials from Carolina Biological Supply or another company Camera to capture images of flies and fly equipment Blank paper to draw fly phenotypes, etc. After hours usually before you leave work collect all females that are present.

When writing the genotype, in general, chromosomes are separated with a semicolon. This can be constructed by using the top of a petri dish, adding crushed ice, then placing the bottom of the petri dish on top.

A Place a funnel in the mouth of a fresh culture vial that already has media added. Return to the lab and choose "use fly in new mating" under the microscope view.

One requires no anesthetizing but quick hands. Females remain virgins for only hours after eclosure and must be collected within this time frame.
