Relationship between various chromosomal changes in Drosophila melanogaster

Demerec, Milislav (August 1937) Relationship between various chromosomal changes in Drosophila melanogaster. Cytologia, Fuji J. pp. 1125-1132.



From a total of 61 Jethals affecting known loei of the X-chromosome, and induced by X-ray treatment of 2500 to 3000 r-units, 26 or 42.6 per Cent had ehromosomal aberrations such as inversions and translocations. In 92.3 per cent of cases one breakage point of the chromosomal aberration coincided with the region where the lethal change took place. Of 30 visible mutations induced by a similar treatment only one carried a chromosomal aberration. This, however, did not coincide with the region where visible change took place. Data available an 80 spontaneous Jethals show that none was conneeted with either an inversion or a translocation. Among Jethals induced by X-ray treatment, the frequency of such chromosomal aberrations increases with the increase of dosage.
