Figure 2. Different laboratory strains of wild-type Drosophila have different lifespans.

Each genotype was raised in parallel under the same conditions and assayed on 1× SY for lifespan. All strains that were tested exhibited a shorter lifespan than our outbred laboratory strain Dahomey. The graph legend reports the strain name; median lifespan in days and; p-value from the log-rank test when compared to Dahomey.
