a) Growth of Saccharomyces type strains inoculated into medium containing 1% glucose and 1% galactose. b) Geometric means of the growth rates (GMR) from a, normalized to the analogous quantity in glucose medium. c) Growth of S. cerevisiae isolates (blue) from the indicated populations (W/E, Wine/European; W.A., West African; N.A., North American) and the S. bayanus type strain (black), inoculated into medium containing 1% glucose and 1% galactose. d) Growth (solid lines) of S. cerevisiae and S. bayanus inoculated into medium containing 1% glucose and 1% galactose, and medium concentrations of glucose and galactose (dotted and broken lines, respectively). Error bars report standard error of the mean.
