Mating experiments were performed at 27 degrees C, 22 degrees C, and 17 degrees C, to investigate the inheritance of adult life span of highly inbred strains of Drosophila melanogaster. Effects of temperature difference were quantitatively analyzed at the genotypic level. In the temperature range of 17-27 degrees C the autosomal longevity alleles, A1 and A2, exerted major effects. Their effects produced longer life spans as the temperature decreased. The sex-linked longevity alleles, X1 and X2, played a secondary role in influencing life span, and they displayed different effects at different temperatures. Each genotype showed correspondence to the life span expected from the combinations of these longevity genes at the respective temperatures. The genetic loci controlling life span in these inbred strains were named JmA and JmX from "Ju-myo" which means life span or longevity in Japanese.
