Abbreviations: P{e(y)1+}-21 and P{e(y)1+}-22 are different single insertions of P{e(y)1+} in the second chromosome; P{Δe(y)1}-2 is a single insertion in the second chromosome; P{Δe(y)1}-3 is a single insertion in the third chromosome. The level of viability was calculated as a ratio of males carrying e(y) mutations to FM4 males. For each combination of mutations no less than 200 FM4 males were scored.
