eggG19561 mutants possess ovaries of a markedly reduced size compared with wild-type flies. eggG19561/Df(2R)ED4065 mutants exhibit a slightly more severe phenotype than eggG19561 mutants. Homozygous mutant females are unable to lay eggs, and are therefore sterile. Mutant ovaries carry egg chambers, but these are mostly degenerated in appearance.
Su(var)3-917, eggG19561 has ovary phenotype
Su(var)3-917, eggG19561 has egg chamber phenotype
eggG19561; Su(var)3-917 double mutants mostly exhibit a gourd-shaped germaria and defects in the budding off of new egg chambers; as a result, the double mutant has no developing egg chambers in the ovary.
