The disjunction of a series of X chromosome deletions (constructed by deleting, with x irradiation, all but a negligible amount of the euchrozmatin of the X and a variable amount of the proximal heterochrozanatin) was studied in X/X/ Del females, attached-X/Del females, and attached-XY/Del males. With one interesting exception, the data agree with the nations of Gershenson. The exception was found in the results from matings of males carrying the attached XY chromosome and certain of the deletions. Among their progeny the deletion is recovered in constderably more than half of the individuals whereas tae XY is recovered in considerably less than half. The following points have been established: Egg counts have shown that this is not zygote mortality. The fact that the deletions are recovered in excess of 50 percent of the progeny elizaninates meiotic chromosome loss as the explanation of the discrepancy. Evidence is presented indicating an autosomal influence on this phenomenon. Finally, it has not yet been possible to determine the physical basis of these results. However, it appears that whatever the physical basis, this phenomenon could cause meiotic drive in a population. (auth)
