Scale invariance in Drosophila segmentation
Check out our new discovery here :)you can rerun the program here.Despite unavoidable fluctuations in egg or embryo size, the gene expression pattern and hence the embryonic structure formed through development often scale with body size, known as the scaling or scale-invariance phenomena. Scale-invariant patterning of gene expression is a common feature in development and regeneration, and has...
