The morphology of the optic stalk is severely disrupted in CdGAPrNP3053/CdGAPrNP3053, CdGAPrEY13451/CdGAPrNP3053 and CdGAPrNP3053/Df(2L)ED1303 animals.
CdGAPrNP3053 has embryonic/larval optic stalk phenotype, enhanceable by FakCG1/Fak56D[+]
CdGAPrNP3053/CdGAPr[+] is an enhancer of embryonic/larval optic stalk phenotype of FakCG1
CdGAPrNP3053 Fak56DCG1 double heterozygotes show severe defects in optic stalk morphology, in contrast to either single heterozygote, which show only slight defects in optic stalk formation.
