A similarity measure between tandem duplication trees

This paper opens the gate to understanding the nature of unequal crossing-over process, which is one of the mechanisms that leads to creation of new genes. The Data Mining and Tree Mining approaches are being modified to fit that particular biological problem. The novel notions: the similarity of duplication process and the similarity of a duplication region are proposed, and settled as the fundament of further analysis. The role and applications of the duplication process similarity measure are discussed. The roadmap for further extensive studies together with first interesting results are presented.
