Two replicates were performed for each strain (A and B). The name of experimental strains is given as Sx-RAG, where Sx is the name of the original wild-type strain, R is the replicate (A or B), and AG is the number of "asexual generations". The duration of the experiment is given in number of AGs and number of days. The "intercept" (a) and "slope" (b) of the Poisson regressions y = ea+bt (y: number of perithecia produced by the evolved strain, t = number of AGs) and t50 are given for each evolved strain with the two reference strains (1st and 2nd ref.). R2: Coefficient of determination for each adjustment. ρ: Pearson's coefficient for the correlation between female fertility (= number of perithecia produced) and male fertility (= number of perithecia induced) for each strain against each reference strain in each replicate (* indicates values significantly different from 0, test for association between paired samples)
