Philip Rock has developed a number of lines for demonstrating various genetic principles (sex linkage, segregation etc) in Drosophila. These stocks carry many mutations commonly used for teaching in combination with an apterous allele (ap[56f]) which renders the flies flightless. Theoretically, using these will result in fewer flies roaming around the building and showing up in your colleague's offices down the hall.
For some notes on these stocks from Rock, click here.
**The 'Genes" and 'Chr' columns ignore the presence of the apterous allele and list only the genes and chromosome locations for the non-apterous mutations.
