First file, LS.sav, is lifespan data looking at interactions of sex, nuclear and mitochondrial genotypes on lifespan. Second file, Survival Data.sav, is male lifespan data looking at interactions of nuclear and mitochondrial genotypes, food and rearing environments on lifespan. Third file, d14.sav, is climbing data for males (height in 15secs) from Survival Data.sav, measured on day 14 looking at interactions of nuclear and mitochondrial genotypes, and food type. Triplicate (techrep) is nested within biolrep which is nested within nuclear x mitotype x food type.
