3. REVEALING TRADE-OFFS: THE USE OF MULTIVARIATE 
QUANTITATIVE GENETICS 
3.1. Life-History Trade-Offs and Genetic Correlations 
The existence of trade-offs between different components of fitness is fundamental to much of 
life-history theory. If these constraints are to affect evolutionary processes, which evolutionary 
ecologists typically assume they will, they must have a genetic basis, requiring the action of either 
antagonistic pleiotropy or linked genes with antagonistic effects, and the...
