Statistical table

	Data structure	Type of test	Power (f = 0.25)
a		Χ²	0.999
b	N too small to determine if normally distributed	One-way ANOVA	0.0001
c	N too small to determine if normally distributed	One-way ANOVA	0.471
d	N too small to determine if normally distributed for 3 of 4 genotypes. The fourth genotype with 8 animals is normally distributed.	One-way ANOVA	0.274
e	N too small to determine if normally distributed for 3 of 4 genotypes. The fourth genotype with 8 animals is normally distributed.	One-way ANOVA	0.632
f	N too small to determine if normally distributed for 3 of 4 genotypes. The fourth genotype with 8 animals is normally distributed.	One-way ANOVA	0.493
g	N too small to determine if normally distributed for 3 of 4 genotypes. The fourth genotype with 8 animals is normally distributed.	One-way ANOVA	0.350

Post hoc power calculations for each statistical test reported are recorded in this table. To calculate post hoc power, we used an effect size of 0.25, a sample size that was the minimum group size, and the actual p value returned by the indicated test. For almost all instances, we were unable to formally test whether the data were normally distributed because the sample size was not 8 or greater. Superscript letters in the figure legends refer to the first column of the table.
