The embryonic cuticular phenotype (dorsal closure defects) and lethality of yrt3 homozygous mutants is significantly suppressed by combination with either chem1 or chem3 in heterozygous state and some of the animals progress to larval stage. Over half of yrt3/yrt3;chem1/+ larvae (when cultures separately) manage to pupariate. Conversely, the embryonic phenotypes of chem1 or chem3 homozygotes are slightly but significantly improved by combination with a single copy of yrt3. The cuticular phenotype of either yrt3;chem1 or yrt3;chem3 double homozygous embryos is improved relative to yrt3 single mutants but worsened relative to either chem1 or chem3 homozygotes.
