Fig. 3From: The distance and median problems in the single-cut-or-join model with single-gene duplicationsAn example of the reduced genome r(X), of the genome X. Note that an instance of \(h_hh_t\) is retained so that r(X) contains at least one representative of gene family h. All observed duplications are removed in r(X). Here, \(t(X) = |X - r(X)| = 5\)Back to article page
