Inversion of sequences between the insertion point of P{lArB}A208.1M2 and P{lArB}slp1A509.
one breakpoint of slp1Delta1E; an inversion of sequences between two P insertions.
Weak slp1 cuticle phenotype affecting the odd numbered segments. Structures of the cephalopharyngeal skeleton are missing.
Phenotypic analysis of different slp1 and slp2 alleles establishes an allelic series: slp11 < slp1Δ41E < slp1A509 < slp13 < slp1Δ46G < slp2Δ66C < slp1Δ34B = slp2Δ34B.
