Heterozygotes are WT and GFP+ in the pharynx. qIs48 is an insertion of ccEx9747 (carries myo-2::GFP, pes-10::GFP, and a gut enhancer fused to GFP) onto the hT2 chromosome and is homozygous lethal. Presence of ces-1 is inferred from strain construction but not experimentally verified. Note: qIs48 has been observed to recombine off hT2, typically leaving behind a functional homozygous viable hT2 with Bli-4 phenotype.

Heterozygotes are Ces and segregate VulUncs and dead eggs. ces-1(n703) is dominant. Do not distribute this strain; other labs should request it from the CGC. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.
