Physical performance traits are key components of fitness and direct
targets of selection. Maternal effects are important components of
integrated phenotypes in a variety of species. Yet their contribution to
variation in performance, and phenotypes closely associated with
performance, remains poorly understood. We used an animal model approach
to quantify the contribution of maternal effects to performance trait
variation (in bite force and pull strength) and the relationships between
performance and the relevant underlying morphology in Microcebus murinus.
We show that bite force is heritable (h2~0.23), and that maternal effects
are also important source of variation, resulting in a medium inclusive
heritability (IH2~0.47). Grip strength presented a rather low and
non-significant narrow-sense heritability suggesting a higher selective
pressure on this trait. Genetic correlations between performance traits
and their associated morphometric traits were significant and high (0.47
bite force-head width; 0.48 grip strength-radius length), as was the
maternal correlation for bite force-head width (0.75). Further studies
evaluating the heritability of performance for other taxa and the role of
maternal effects are badly needed to better understand the drivers of
variation in performance ultimately allowing for a better understanding of
the importance of these types of traits in an evolutionary context.
