Heritability and developmental plasticity of growth in an oviparous lizard.

ABSTRACT: Selective processes act on phenotypic variation although the evolutionary potential of a trait relies on the underlying heritable variation. Developmental plasticity is an important source of phenotypic variation, but it can also promote changes in genetic variation, yet we have a limited understanding of how they are both impacted. Here, we quantified the influence of developmental temperature on growth in delicate skinks (Lampropholis delicata) and partitioned total phenotypic variance using an animal model fitted with a genomic relatedness matrix. We measured mass for 261 individuals (n_hot = 125, n_cold = 136) over 16 months (n_observations = 3002) and estimated heritability and maternal effects over time. Our results show that lizards reared in cold devel
