Homeobox genes

Homeobox genes are a group of genes that control the development of an organism's body plan during early growth. They contain specific DNA sequences called homeoboxes that produce proteins acting as genetic "master switches," directing cells on how to develop into different parts like limbs, organs, or tissues. These genes are highly conserved across species, indicating their fundamental role in shaping biological form. In essence, homeobox genes guide the orderly formation and organization of an organism's body structure from a single fertilized egg.
