Syntenic distance : a survey

The term synteny was coined in the seventies and refers to the property of two genes being on the same chromosome (see the American Heritage Dictionary of the English Language). The syntenic distance was introduced in 1996, [5] in order to infer phypogenies of a set of species. In this model the relative positions of the genes are irrelevant, the important fact is the assignement of chromoses to genes. As usual, the criteria to judge the likelyhood of a phylogeny is based on a notion of distance between species. This is the topic under study in this survey.
