Comparative phylogenetic  and experimental evolution  studies suggest an inherent mechanism for robust generation of a scaled Bicoid protein gradient. Bicoid is a maternal effect gene whose protein concentration gradient patterns the anterior-posterior A-P axis during Drosophila embryogenesis.

Mechanisms that have been proposed to effect this scaling include non-linear degradation of Bicoid,  nuclear retention as a protin regulator of Bicoid protein’s effective diffusion coefficient,   and scaling of cytoplasmic streaming. The protein is concentrated in the nuclei of cleavage stage embryos.
