It is, in fact, one of the great disciplines-at the nexus of developmental biology and genetics-it studies how genes regulate the development of organisms from a single cell into a highly complex multicellular organism. It is also one of the most important regions of research because it attempts to explain the intricate mechanism by which embryonic development, differentiation of tissues, and organogenesis take place.

Investigators in developmental biology and genetics explore how genetic instructions encoded in DNA are translated into physical structures and functions in living organisms. All of these-the genes themselves, the expression patterns of their products, the signaling pathways by which they act, and mutations that alter them-seem to affect such development processes. If genes responsible for creating limbs, eyes, or other parts are not meant to develop improperly then they must be highly controlled.

One of the most important concepts of developmental genetics is regulatory genes that have the activity to make certain genes inactive or active. Amongst such a list of regulatory genes, Hox gene is the most important for building up a body plan so that right organs and tissues arrive at the right locations in appropriate sequences. Such mutations cause developmental disorders and congenital anomalies.
