Biallelic disruption of golden (gol) by Cas9 targeting a second location at the gol locus (gol target 2) generates similar mosaic pigmentation phenotypes. gol gRNA (gol target 2) (50 pg) and nls-zCas9-nls RNA (150 pg) were injected into wild-type embryos. Lateral (A–C) or dorsal (A2–C2) views of wild-type (A and A2) and gol-targeted embryos (B–C2) at 2 dpf. Whereas the wild-type embryo showed darkly pigmented retinal pigment epithelium (RPE), gol-targeted embryos had patches of unpigmented cells in RPE. The skin melanophores in gol-targeted embryos were also hypopigmented. The phenotypes were indistinguishable from those generated by the other gol-targeted gRNA shown in Fig. 4.
