The new organism has half the chromosomes from its mother and half from its father. Source from ...

This is well documented in Advances in Microbial Physiology, Volume 16, Moseley and Williams, pages 116-117 (searchable via Google Books). Mattern et al. (1966) designated mutations that made E. coli Bs-1 sensitive to X-ray radiation as exr (X-ray sensitivity) mutations. That same year, Howard-Flanders and Boyce (1966) independently designated equivalent ...
