Event probabilities in biphasic amplitude filter.

<p>Probabilities of events in the biphasic amplitude filter as a function of the input protein level . The solid black line denotes the probability that the output gene D is expressing, while the dark gray lines denote those of the intermediate genes (solid denoting gene B and dashed gene C). The probabilities that the intermediate genes allow the output gene to express are depicted by the light gray lines (solid denoting gene B and dashed gene C).
