The networks indicate differences with respect to their topological features. The degree distribution, which implies the total number of links attached to a gene, is one of these features. In biological networks, the number of incoming links and out-going links have distinct names and are expressed by various distributions. The former implies the in-degree and is typically represented by the exponential distribution. On the other hand, the latter refers to the out-degree and is presented by different distributions such as power-law, generalized pareto-low and geometric distributions. In this study, by using real systems under various dimensions, we investigate the validity of these alternatives and test whether the out-degree distribution can be represented by one of the families in the Pearson system.
