χ2 test results of observed versus expected Inv+ and Inv- frequencies among progeny from single apothecia of four parental strains, screening results are in Table S6.

AInv+ and Inv- frequencies were expected to be equal.BNone of the Inv+:Inv- ratios differed significantly from 1.A. 预期AInv+与Inv-的频率相等。B. 所有Inv+:Inv-的比值均未显著偏离1。
