Abstract
AUERBACH1,2,3,4 reported that the exposure of adult males to the vapours of allyl isothiocyanate increases the mutation-rate in Drosophila melano-gaster. About a fifth of the lethals thus produced were found by Slizynska and Slizynski5 to be connected with cytologically detectable deficiencies, and in addition, there were about 7 per cent of gross structural changes. Auerbach2 found also that the same chemical treatment of female embryos leads to high frequency of mosaicism, which is almost solely due to somatic crossing-over.
