Fig. 2

Wild-type and al1 CRISPR/Cas9 knockout forewings of white and yellow H. cydno. A Full adult forewing view of wild-type and al1 knockouts of both white and yellow H. cydno. Blue arrowheads highlight mutant yellow clones inside the white regions and red arrowheads highlight mutant brown clones inside the melanic regions of wing. B Higher magnification view of the mutant parts of the wing for both white (top panel) and yellow (bottom panel) H. cydno butterflies. Dashed blue lines highlight the parts of the clone that switched from white to yellow and dashed red lines highlight the parts of a clone that switched from black to brown. Higher magnification views highlighting al1 mutant clones for both white and yellow wings are shown on the right of each color morph image with both clone level view (top) and scale level view (bottom)
