Strain | [psi^{–}] | Unstable | Stable | Total | % [ psi^{–}] ± SD |

L1767 | 2199 | 2221 | 0 | 4420 | 49.7 ± 19.3 |

L1768 | 947 | 1360 | 0 | 2307 | 41.1 ± 8.7 |

L1769 | 1214 | 740 | 0 | 1955 | 62.1 ± 6.7 |

The percentage of [*PSI*^{+}] loss and the standard deviation (±SD) were calculated for three 74-D694 unstable [*PSI*^{+}]by spreading at least three independent colonies from each to YPD plates and scoring the resulting colonies as *[psi*^{–}], unstable [*PSI*^{+}] (sectored), or stable [*PSI*^{+}].
