How To Use Homeotic gene In A Sentence

Changes to homeotic genes cause monstrosities (two heads, a leg where an eye should be, etc.); they do not change an amphibian into a reptile, for example.
He and his group have discovered the homeobox, a DNA segment characteristic for homeotic genes which is not only present in arthropods and their ancestors, but also in vertebrates up to man.
Genes identified by such mutations are called homeotic genes because when mutated they result in homeosis - the transformation of a whole segment or structure into another related one, as in the transformation of antenna to leg.
These genes encode proteins that are involved in regulating the expression of homeotic genes by changing chromatin structure.
Several genes involved in the regulation of chromatin structure were identified as regulators of homeotic gene complexes.

This caused other homeotic genes to respecify this particular segment into one that forms wings. Physiology or Medicine 1995 - Press Release
Inactivity of the first gene of the bithorax-complex in the appropriate larval segment caused other homeotic genes to respecify the 3rd thoracic segment into one that forms wings instead of halteres. Lewis' Discoveries
For example, it is becoming clear that co-option has played a critical role in evolution and the homeotic genes are not exempt in this regard.
