Faster breeding sea urchins: A comeback animal model for developmental biology

University of Tsukuba researchers identified a species of sea urchin with a relatively short breeding cycle of six months. They used CRISPR technology to remove a gene that provides pigment. Male albino sea urchins survived. Crossing these with wild-type sea urchins and then breeding the offspring yielded second-generation albino mutants that matured to adulthood.
