Complementation section: instability frequencies and genome fold stabilization of ERV14 complementation of rad9Δ erv14 normalized to rad9Δ erv14; ERV14 copy number section: instability frequencies and genome fold stabilization of rad9Δ with extra copies of ERV14, normalized to rad9Δ. Cells with a light gray background indicate genome fold stabilization increase; cells with a white background indicate decreased fold stabilization (<1.0 = increased instability) or no change in stabilization (=1.0). Statistically significant appears in boldface type. Kruskal–Wallis test, * P < 0.01.
