Viability studies of myb mutants at different temperatures. myb¹, myb², and myb²;P(w⁺,myb⁺) animals were raised at 18°C and kept at this temperature for 5 days after the adults emerged from their pupal cases. They were then divided into groups and incubated at the indicated temperatures. Batches of embryos were collected over the next 2 days and the percentage of animals that hatched into larvae, pupated, and emerged as adults was monitored. Number of batches tested for each genotype and temperature is indicated in brackets. Standard deviations are shown in parentheses.
