Dividing genes

Verified step by step guidance

Understand the role of each gene group mentioned in the options. Segmental genes are involved in the segmentation of the body plan, but not specifically in the anterior/posterior or dorsal/ventral patterning.

HOX genes are a subset of homeotic genes that play a crucial role in determining the identity of body regions along the anterior-posterior axis. They are highly conserved across species and are key in patterning.

Patterning genes is a broader term that encompasses genes involved in establishing the spatial organization of tissues and organs, including anterior/posterior and dorsal/ventral axes.

Dividing genes are not a standard term in developmental biology related to body region development. They might refer to genes involved in cell division, but not specifically in body patterning.

Based on the definitions, HOX genes are the most specific group of genes that control the development of different body regions, particularly along the anterior/posterior axis.
