  1. Analysis of gene expression was performed pair wise for a set of embryo experiments (1–8) using pools of 5 eggs while single juveniles were used in experiments 9–16. Staging of embryos and juveniles is assessed by key developmental parameters as described in the text. For embryos the number of somites in the part of the tail that is detached from the yolk as well the observed tail curvature is given. The number of somites is an approximation as it was determined in vivo. For juvenile fishes we provide the total body weight in gram.
