capt¹⁰ chb⁴ double heterozygous embryos do not show a significant increase in axons ectopically crossing the midline compared to controls. capt¹⁰ chb^P4 double heterozygous embryos do not show a significant increase in axons ectopically crossing the midline compared to controls.

Central nervous system axons are seen to cross the midline in Abl⁴ capt¹⁰ double heterozygous embryos. Central nervous system axons are seen to cross the midline in Abl² capt¹⁰ double heterozygous embryos. Src64B^PI capt¹⁰ double heterozygotes do not show significant midline crossing defects in the embryonic central nervous system. The frequency of ectopic crossing of the midline by axons in the central nervous system seen in sli² heterozygous embryos is increased if they are also heterozygous for capt¹⁰. capt¹⁰ lea^robo2-4 double heterozygotes show little if any midline crossing defects in the embryonic central nervous system. capt¹⁰ robo3¹ double heterozygotes show little if any midline crossing defects in the embryonic central nervous system. One copy of capt¹⁰ does not enhance the frequency of midline crossing defects seen in robo¹ robo3¹ double mutant heterozygotes. capt¹⁰/Df(2L)ast2 embryos show 54% ectopic midline crossing by axons in the central nervous system.

Ectopic actin filaments do not form in capt¹⁰ chic^05205a double mutant follicle cell clones, and the level of F-actin in these cells appears to be similar to that in chic^05205a single mutant cells. Cells in capt¹⁰ chic^05205a double mutant follicle cell clones lose their columnar morphology and collapse, forming a thin squamous-like layer of cells. These clones can interfere with the migration of wild-type portions of the follicle cell epithelium. The double mutant clones maintain extensive contacts with adjacent wild-type cells. F-actin is often seen accumulating at a single, randomly positioned site within the cell in capt¹⁰ l(2)gl⁴ double mutant follicle cell clones. Ectopic actin filaments do not form in ena^unspecified capt¹⁰ double mutant follicle cell clones and F-actin levels are often decreased. Expression of Abl^Scer\UAS.cFa under the control of Scer\GAL4^T155 in capt¹⁰ mosaic egg chambers alters both the level and distribution of actin filaments in the capt¹⁰ mutant cells. In a few egg chambers, the epithelial morphology is profoundly disrupted.
