Abstract
THE ability of 150 larvæ to emerge as adults under 6 different temperature regimes for 3 inbred lines, their hybrids and the F 2 generation has been studied in Drosophila melanogaster 1. This work revealed that interactions between genotype and environment were smallest in the F 1 generation and largest in the inbred lines. The F 1's therefore show a higher degree of stability or homeostasis than the inbred lines. The F 2 gave a genotype × environment interaction intermediate between the F 1 and the inbred lines, as might intuitively be expected because of segregation in the F 2.
