Galled trees are studied as a recombination model in theoretic populationgenetics. This class of phylogenetic networks has been generalized totree-child networks, normal networks and tree-based networks by relaxing astructural condition. Although these networks are simple, their topologicalstructures have yet to be fully understood. It is well-known that allphylogenetic trees on $n$ taxa can be generated by the insertion of the $n$-thtaxa to each edge of all the phylogenetic trees on $n-1$ taxa. We prove thatall tree-child networks with $k$ reticulate nodes on $n$ taxa can be uniquelygenerated via three operations from all the tree-child networks with $k-1$ or$k$ reticulate nodes on $n-1$ taxa . An application of this result is found incounting tree-child networks and normal networks. In particular, a simpleformula is given for the number of rooted phylogenetic networks with onereticulate node.
