Cave animals provide a compelling system for investigating diverse morphological, developmental, and behavioral traits. But one of the limiting factors in establishing this model system is a lack of genetic tools that would allow us to manipulate

We describe approaches for the manipulation of genes in the evolutionary model system Astyanax mexicanus. Three different techniques are described: Tol2-mediated transgenesis, targeted manipulation of the genome using CRISPR/Cas9, and knockdown of expression using morpholinos. These tools should facilitate the direct investigation of genes underlying the variation between surface- and cave-dwelling forms.
