Young Innovators: Mutated frog gene repels predators

The incredible colour patterns of Colombian dart frogs have long been a mystery, but now University of Saskatchewan researchers have identified the gene responsible for the black blobs and stripes that make the colours stand out.
Post-doctoral researcher Andrés Posso-Terranova and his former supervisor José Andrés have found evidence that a single gene called MC1R controls the deep black colour on the skin of these poisonous frogs. The researchers have found that the disrupt
