Caption

The mouse on the left is a chimeric with dark eyes and patches of black fur, a result of stem cells derived from a choanoflagellate Sox gene. The wildtype mouse on the right has red eyes and all white fur. The colour difference is due to genetic markers used to distinguish the stem cells, not a direct effect of the gene itself.
