The disomy for chromosome IV in the strains studied led to: reduction in the red pigmentation of ade1 mutant colonies; a decrease in spontaneous rho- mutant frequency, and impairment of sporulation in hybrids descended from disomic parents. The nuclear srm1 mutation decreasing the spontaneous rho- mutability promoted the spontaneous extra chromosome loss in the disomics for chromosome IV. This result suggests a close connection between the spontaneous rho- mutability and mitotic chromosome stability.
