Abstract
Two three-break shifts (transpositions) are detected in a chromosome comparison betweenD.n. nasuta andD. kohkoa. Such aberrations are not reported in studies with chromosome comparisons inDrosophila species. The probable sequences are given to explain the occurrence of these transpositions.
