Egg size and offspring phenotype data at early life stages in seven Arctic charr morphs ...
Maternal effects have the potential to alter early developmental processes of offspring and contribute to adaptive diversification. Egg size is a major contributor to offspring phenotype, which can influence developmental trajectories and potential resource use. However, to what extent intraspecific...

Maternal effects have the potential to alter early developmental processes of offspring and contribute to adaptive diversification.
