Counterbalancing effect of JIL-1 and Su(var)3-7 loss-of-function alleles on PEV in the eyes of w^m4 flies. (A) Examples of the degree of PEV in the eyes of wild-type JIL-1 and Su(var)3-7 (wt), JIL-1^z2/+ (z2/+), Su(var)3-7^7.1A/+, and JIL-1^z2 Su(var)3-7^7.1A/+ (z2, 3-7^7.1A/+) flies in a w^m4 background. All images are from male flies. (B) Histograms of the distribution of the percentage of red ommatidia in wt, JIL-1^z2/+ (z2/+), Su(var)3-7^7.1A/+, and JIL-1^z2 Su(var)3-7^7.1A/+ (z2, 3-7^7.1A/+) male flies in a w^m4 background.
