TABLE 1.

Mean (SE) and variance of sexual fitness (sporulation rate) and asexual fitness (growth rate) among ancestral, SMA, and LMA lines of Saccharomyces cerevisiae

	Sexual		Asexual
	Mean	Variancea	Mean	Variance
t = 0	0.6754 [a] (0.004)	0.0020 [a]	0.2773 [a] (0.0009)	1.12 × 10−4 [a]
SMA t = 800	0.6245 [b] (0.016)	0.0210 [b]	0.2734 [b] (0.0015)	1.72 × 10−4 [b]
LMA t = 800	0.7484 [c] (0.005)	0.0013 [a, b]	0.2809 [c] (0.0015)	1.15 × 10−4 [a, b]

Results with different letters [a, b, c] are significantly different according to randomization tests on the difference between means or the difference between variances.

^aVariance of the raw data. Randomization tests were performed on arcsine-transformed proportions.
