CRISPR Gene-Editing Has Opened Doors for Exotic Model Organisms

Scientists are trying to move beyond conventional model organisms, like fruit flies, zebrafish, yeast, and mice. They started using CRISPR gene-editing technology to craft new model organisms or to study the animals that they are more interested in. The genetic alterations generally take hold but the practical challenges of breeding and maintaining unconventional lab animals persist.
