Weak recessive allele of mua-3. 40% have muscle detachment from cuticle in adults, primarily in head, results in weak bent head phenotype. 60% are wild type.

Animals with the duplication are WT and segregate WT and larval lethals. Larval muscle dettachment and arrest at about L1 stage in mua-3(ar62) homozygotes. 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.
