This Article contains typographical errors in the Results section under subheading ‘Between-population and within-population variation of relative body depth’.“The mean relative body depth of the triploid asexual Japanese crucian carp differed significantly among 13 populations (Fig. 3, Welch’s one-way ANOVA weighted for unequal variances, F12,67.08 = 26048, P < 2.2 × 10−16). The total variation in the relative body depth was 45% explained by the between-population variation and 55% by within-population variation (Kulinskaya and Staudte’s weighted coefficient of determination, ρ2 = 0.45). Within-population variation in the relative body depth was significantly different among populations (Fig. 3, Levene’s test of homogeneity of variances: F12,420 = 12.48, P < 2.2 × 10)”.should read:“The mean relative body depth of the triploid asexual Japanese crucian carp differed significantly among 13 populations (Fig. 3, Welch’s one-way ANOVA weighted for unequal variances, F12,67.08 = 26.48, P < 2.2 × 10−16).
