A survey of the effect of copy number variation on halothane potency. EC50 values for 220 deletion heterozygotes were estimated as described in Materials and Methods. Each strain was assigned a rank based on the percentage difference between its EC50 value and that determined in parallel for the control strain. The figure presents these differences as a function of rank number. Note that very few of the strains can be reliably distinguished from control line because the shift in their EC50 falls within the region of experimental uncertainty (gray shading).
