Figure 2.—

Illumination effects on anesthetic depth in white mutants. Halothane sensitivity was determined in dim red light or ambient light as in Figure 1 for Cantonized strains bearing either the w¹¹¹⁸ mutation (A) or the w^hd80k17 (abbreviated as w^hd) mutation (B). EC50 values and slope constants for each curve are given in Table 1.
