: Earlier this year, researchers used single-guide RNAs with a fluorescent tracer to alter pigment genes in embryos of the African clawed frog (Xenopus laevis
). The treatment resulted in the right half of embryos lacking pigment, as shown in the neurula stage (top) and at a later developmental period (bottom).

) and skin appendages in terrestrial animals, according to recently published research.
