Distribution of single parameters for model architectures with an essential negative, an essential positive, or essential positive and negative feedback loops. The top, central, and bottom panels show the distribution of single parameters involved in the negative loop, positive loop, and not involved in any loop, respectively. Black, blue, and green boxplots correspond to parameter points that define architectures based on an essential negative loop, an essential positive loop, or essential positive and negative loop, respectively.
