[edit] Norm of reaction for bimodal morphology

I created an illustration based on those in Norms of reaction to illustrate a canalising trait. Perhaps someone better familiar with the concept of this article can let me know if this is a helpful presentation, or if the graph should perhaps be modified in some manner. I did not make the two "plateaus" strictly horizontal, but allowed a minor variation within each of the bimodal forms... that seemed more realistic; but the variation within a morphological form is much less than the variation between the forms.

[edit] Mutations or environment?

This article says that canalisation means, that a phenotype is robust against environmental changes because of its genotype. However, this article (Rando and Verstrepen, Timescales of genetic and epigenetic inheritance, Cell 128, 655-668, 2007) says this insensitivity of a phenotype to genetic mutation is often referred to as 'robustness' or 'canalization'. So whats the correct description? 212.45.53.58 12:16, 21 April 2007 (UTC)
