Detailed explanation-1: -The role of the Hox genes is to specify positional identity in the embryo rather than the development of any specific structure. These positional values are interpreted differently in different embryos to influence how the cells in a region develop into, for example, segments and appendages.
Detailed explanation-2: -There is an overwhelming amount of data that support that Hox genes are critical for patterning the axial skeleton in vertebrates and that changes in Hox gene expression have helped shape the evolution of novel body plans within Bilateria 4, 5.
Detailed explanation-3: -While there are a great many genes that play roles in the morphological development of an animal, what makes Hox genes so powerful is that they serve as master control genes that can turn on or off large numbers of other genes.
Detailed explanation-4: -why have small changes in hox genes had such a great effect on the evolution of animal diversity? small changes in the development of an embryo can cause large changes in the body of the adult, such as the number of legs or the size of the limbs.
