Calculation parameters included admixture group measurements with n = 30 (df = 3). The significant p-value confirmed that variance existed between (indicated by bold typeface). A post hoc Tukey HSD test compared the group means using mean square error. Significant results are indicated by bold typeface. These results reveal that the strains of mice with the same nuclear ancestry have respiration levels significantly different from each other.
