Comparative phylogenetic [16] and experimental evolution [17] 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, [18] nuclear retention as a protin regulator of Bicoid protein’s effective diffusion coefficient, [9] [19] and scaling of cytoplasmic streaming. The protein is concentrated in the nuclei of cleavage stage embryos.
