|Characteristics||A 401bp deletion was generated by CRISPR/Cas9 in the region harboring ZRS enhancer (Intron 5 of Lmbr1 gene, chromosome 20). ZRS enhancer drives expression of shh gene to pectoral fin buds. CRISPR targeted sequences are GTGAGTAATCAATTAAACGAGG and GTCCAGCTGTATTACCATGCAGG. The original background of this mutant is Cab strain. In pectoral fin buds, shh gene expression is reduced. In adult pectoral fins, the number of proximal radial bones is reduced.|

Upper pannels, expression of shh at 3 dpf is reduced in pectoral fin buds from ZRS 401 bp deletion mutants.
Lower pannels, the number of proximal radial bones is reduced in ZRS 401 bp deletion mutants.
