Abstract
Alverdes(1) as long ago as 1912 interpreted the bands of the giant chromosomes found by Balbiani(2) in Chironomus as the result of spiralization. Later, Kaufmann,(3) applying plant-chromosome techniques to Drosophila giant chromosomes, concluded that the discoid or discontinuous appearance of these chromosomes was an expression of inadequate technique and that a spiral structure was the more accurate. Nevertheless, the discontinuous structure appeared to fit genetic data more easily.
