Consomic mouse strain selection based on effect size measurement, statistical significance testing and integrated behavioral z-scoring: Focus on anxietyrelated behavior and locomotion

Selecting chromosome substitution strains (CSSs, also called consomic strains/lines) used in the search for quantitative trait loci (QTLs) consistently requires the identification of the respective phenotypic trait of interest and is simply based on a significant difference between a consomic and host strain. However, statistical significance as represented by P values does not necessarily predicate practical importance.
