Investigations using the a B -Sh/2 region of chromosome 3 showed that ultraviolet light (UV) induces about 2.5 times as many apparent gene mutations as ethyl methanesulphonate (EMS). X rays failed to induce any apparent gene mutations but of the three agents compared they induced the highest frequency of chromosomal aberration. Both EMS and UV induced a relatively higher proportion of fractional and a lower proportion of whole-case chromosomal aberrations than X rays.
