The distribution of labeled chromatids at the second mitosis after labeling with tritiated thymidine is random in both Vicia faba (the broad bean) and Potorous tridactylis (the rat kangaroo). This finding is contrary to that predicted by the hypothesis that chromatids containing "grandparent" polynucleotide templates segregate from those containing "parent" templates.
