The expression of these traits often depends on male condition, i.e., condition dependence. Although males often have multiple sexually selected traits, to date many studies have focused on the morphological analysis of one sexual trait whilst ignoring the others.

Usually, several traits in organisms are genetically linked with each other; thus, correlated responses to selection are generally observed. Anti-predator behaviors may be genetically correlated with other traits such as life-history. We compared the life-history traits of individuals derived from two regimes artificially selected for the duration of death feigning in the adzuki bean beetle, Callosobruchus chinensis...
