A comparison of Icheb's chromosomes to those of a typical Brunali male

A chromosome, or chromosome body, is a long, continuous strand of DNA that contains genes and regulatory elements. It is a macromolecular unit of genetic information. Humans had twenty-three chromosome pairs.

Chromosomes could be negatively impacted by:

In 2369, Julian Bashir and Jadzia Dax ran a chromosome scan of a clone of Ibudan. (DS9: "A Man Alone")

In 2372, The Doctor used undamaged chromosomes from Danara Pel's cerebellum to recreate her original DNA code. (VOY: "Lifesigns")

When the Silver Blood USS Voyager and its crew began to deteriorate from subspace radiation in 2375, The Doctor found that their chromosomes were breaking down on a molecular level. (VOY: "Course: Oblivion")

The Brunali made microgenetic alterations in the 3rd, 13th, and 17th chromosomes of certain children so that they would produce a spaceborne virus, turning them into weapons against the Borg. (VOY: "Child's Play")

During an away mission in the Delta Flyer in 2376, Mortimer Harren asserted that genetics, not environment, were the determining factor in personality. In response, Captain Janeway jokingly asked, "How's your thirteenth chromosome? Missing a couple of base pairs in gene 178?" (VOY: "Good Shepherd")
