In the yeast Saccharomyces cerevisiae the disomy for chromosome XIV resembles the previously described disomy for chromosome IV in that it leads to a significant decrease in spontaneous rho- mutability. The nuclear srm1 mutation, reducing spontaneous rho- mutability, diminishes significantly the mitotic disome stability. So, the mechanisms of spontaneous rho- mutagenesis and mitotic disome stability seem to compete for the function affected by the srm1 mutation.
