Fig. 1. Chromosome behavior during and after irradiation-induced mitotic recombination. The clones produced by the two homozygotic daughter cells of a mitotic recombination event are shown below. The photograph shows a shaggy mutant clone, which lacks anti-Myc staining (green), and its sister `twin spot' (+/+), which has a double dose of the Myc epitope, in a pupal wing blade.
