Remove the adult flies from the vial you set up on Tuesday, and count them. If you have fewer than 10 flies, or if you don't have any of the mutant phenotype, add the flies that have eclosed in the old vial since Tuesday to the new vial.
Work on you individual project. Discuss with me any changes I've suggested on your proposal, and talk to me about anything you'll need (mazes, lights, etc.). If you might need virgins in a couple of weeks, make new food vials and transfer some of your pure mutant stock to the new vials. Make vials of food and transfer some pure wild type to them, too.
