mutant zebrafish.

The study, published Feb. 16 in PLOS Biology, made use of
a mutant zebrafish strain that models human Hirschsprung disease, which is caused by loss of the gut neurons that coordinate gut contractions.
Scientists led by John Kuwada, professor of molecular, cellular and developmental biology at the University of Michigan, and Hiromi Hirata of the National Institute of Genetics in Japan originally identified the gene in

CRISPR not only allows researchers to create these animals faster and more precisely than before, but also to move beyond a relatively small menagerie of standard model species — fruit flies, mice,
zebrafish — to create a Noah's ark of
mutant dogs, pigs, primates and more.
