When cactinScer\UAS.cLa is driven by Scer\GAL4arm.PS, flies are fully viable and fertile.
Scer\GAL4arm.PS/cactinUAS.cLa is an enhancer of semi-sterile phenotype of cact7
Scer\GAL4arm.PS/cactinUAS.cLa is an enhancer of embryo phenotype of cact7
The addition of cactinScer\UAS.cLa driven by Scer\GAL4arm.PS to cact7 homozygotes leads to a marked decrease in fertility and an enhancement of the ventralised phenotype.
