This is the notion of the «daughterless gene» - that we could control populations of invasive animals (like carp, toads etc) by genetically manipulating their sex - determining systems.

The origins of many of these and other genes specific to animal processes such as cell adhesion, and social control of cell proliferation, death and differentiation can be traced to genomic events (gene birth, subfamily expansions, intron gain / loss, and so on) that occurred in the lineage that led to the metazoan ancestor, after animals diverged from their unicellular «cousins».

After eight weeks on a high - fat diet, mice that had been engineered with genes to activate the Hedgehog signaling pathway didn't gain weight (left), but control animals whose Hedgehog pathways were not activated became obese (right)(Credit: Long Lab)
