[i] Minimum numbers of genetic events (character changes) required to explain the occurrence of gene family members on human chromosomes 2, 7, 12, and 17, given the phylogenies obtained (see Fig. 1) under the tandem duplication and whole genome duplication models. Genetic events: Dup, tandem duplication; Tra, translocation; Del/Tra, deletion or translocation to another chromosome (i.e., not 2, 7, 12, or 17). Abbreviations of gene family names are as given in Table 1.
