Abstract
THE effect of polyploidy on the radiosensitivity of cells has been the object of some discussion in the past, and it may be of some practical importance in such cases as cancer therapy, for example, since tumours are often mixed diploid–polyploid populations1,2. For chromosomal aberration production by radiation, polyploid sensitivity equal to3,4, greater than3, and less than5,6 the diploid have been reported. Each of the various experiments involved a comparison of different diploid and polyploid species, and the lack of agreement between the experiments may be due to intrinsic differences in species sensitivity, rather than to the effect of polyploidy itself.
