     The hypohaploids may be explained in part by artifacts; however, this explanation can hardly apply to the hyperhaploids. For hyperhaploids the relative frequencies of involvement of single autosomes did not deviate significantly from expectations, assuming the same probability of nondisjunction for all autosomes.
