Homeobox is a DNA sequence which is composed of 180 base pairs and it is found in a particular gene that is known as a homeotic gene. Homeotic gene is a gene whose function is to govern and control the developmental fate of a certain part of a body. These genes control the pattern of the formation of a body in the early embryonic developmental stage of organisms. These genes express such proteins that control the cells in a way that they form different parts of the body.
If the DNA sequence in the homeotic gene undergoes any kind of mutation, it would result in developmental disorders. Homeosis is defined as the phenomenon in which there is a transformation of one organ into the another. It helps the organisms is becoming diverse and hence successful.
