Fig 2. Tests of eggshell assembly in eggs laid by drd homozygous and heterozygous females.

(A) fraction of eggs that lysed during bleach treatment. (B) fraction of eggs that were stained with neutral red after successful dechorionation. ****: significant difference between eggs laid by heterozygotes vs homozygotes, p<0.0001, Fisher’s exact test. Black solid bars: eggs laid by heterozygous control females; red striped bars: eggs laid by homozygous mutant females. The starting number of eggs was 139 from drd^lwf/FM7a females, 115 from drd^lwf/drd^lwf, 225 from drd¹/FM7c, 249 from drd¹/drd¹.
