Slight irregularities in the apical surface of the salivary gland are seen at stage 12 in mutant embryos. By stage 14/15 the salivary gland tube is buckled.
Germ-line clones exhibit a U shaped embryonic phenotype at low penetrance (about 1%).
wb4Y18 has germ band | germline clone phenotype, enhanceable by scb2
wb4Y18 has embryo | germline clone phenotype, enhanceable by scb2
wb4Y18 is an enhancer of germ band | germline clone phenotype of scb2
wb4Y18 is an enhancer of embryo | germline clone phenotype of scb2
No significant overgrowth of the neuromuscular junction is seen in FakN30/FakKG00304 third instar larvae which are also heterozygous for wb4Y18.
