Hox genes are regulator genes that control the development of an organism, including the placement and patterning of body segments. They are not limited to primates and are found in many different organisms. They are not considered to be made up of "junk" DNA, as they perform important functions in development. They are not found in mitochondria and are inherited in the same way as other nuclear genes.
