Excision deletion extending from the P{lacW}Mpp6k16402a insertion site to 11bp after the E2f2 stop codon.
10% of eggs laid by E2f2329 females (Df(2L)E2f2329 homozygotes with Mpp6 function rescued by Mpp6+t4) hatch. 97% of the eggs laid by E2f2329 females have chorion defects. The chorions are more translucent than normal, indicating that the eggshell is thin. In stage 10B through 13 egg chambers of E2f2329 females (Df(2L)E2f2329 homozygotes with Mpp6 function rescued by Mpp6+t4), BrdU incorporation is seen throughout the entire follicle cell nuclei, rather than in characteristic subnuclear foci (which is seen in wild type). The follicle cells do not undergo an additional endocycle in these females. The number of BrdU positive follicle cell nuclei in pre-stage 10B egg chambers of these females is similar to wild type. E2f2329 males (Df(2L)E2f2329 homozygotes with Mpp6 function rescued by Mpp6+t4) are fully fertile. 8% of eggs laid by E2f2329/Df(2L)DS8 females carrying E2f21-188 (Df(2L)E2f2329/Df(2L)DS8 females carrying E2f21-188 with Mpp6 function rescued by Mpp6+t1-188) hatch. 93% of the eggs laid by these females have chorion defects. In stage 10B through 13 egg chambers of E2f2329/Df(2L)DS8 females carrying E2f21-188 (Df(2L)E2f2329/Df(2L)DS8 females carrying E2f21-188 with Mpp6 function rescued by Mpp6+t1-188), BrdU incorporation is seen throughout the entire follicle cell nuclei, rather than in characteristic subnuclear foci (which is seen in wild type). The follicle cells do not undergo an additional endocycle in these females.

An E2f2329 mutant background dominantly enhances the Scer\GAL4GMR.PF>lin-52GD12885 eye phenotype. This is accompanied by a corresponding increase in hid protein and elevated apoptosis in the eye-antennal disc.
The ectopic genomic replication that is seen in the follicle cells of stage 13 E2f2329/E2f21-188 egg chambers is partially suppressed by Orc2γ3/+ or Mcm2rL074/+; there is an approximate 65% reduction in the number of follicle cells within an egg chamber that display ectopic genomic replication and there is an apparent reduction in the intensity of ectopic BrdU incorporation.
The ectopic genomic replication that is seen in the follicle cells of stage 13 E2f2329/E2f21-188 egg chambers is partially suppressed by Orc51; the phenotype is suppressed in 36% of egg chambers.
The ectopic genomic replication that is seen in the follicle cells of stage 13 E2f2329/E2f21-188 egg chambers is partially suppressed by E2f91/+; 55% of the double mutant egg chambers show a 50% reduction in the number of follicle cells exhibiting ectopic genomic replication compared to the single mutant egg chambers.
