Three mutants have been isolated in which the normal 24-hour rhythm is drastically
changed. One mutant is arrhythmic; another has a period of 19 hr; a third has a period of 28
hr. Both the eclosion rhythm of a population and the locomotor activity of individual flies are
affected. All these mutations appear to involve the same functional gene on the X
chromosome.
