Abstract
The incidence of polyploidy (specifically, in this case, the doubling of the stemline chromosome number) induced by x-rays in cells cultured in vitro is about the same for both "near-diploid" and "near-tetraploid" sublines of the Chinese hamster. Endoreduplication is a principal cytological mechanism for this form of induced polyploidy.Keywords
