The species tree shows the phylogenetic relationships for 5 species (A,B,C,D, and E). The 'gene order on chromosome' figure shows different genes (the boxes) arranged on a chromosome. The symbols denote the different functions of each gene. The letters above each box correspond to the gene names. Gene functions are denoted with symbols and gene names refer to the species (letter) and gene function (number). For example, species E has genes 2E (gene 2 in species E) with function "star", 3E (gene 3 in species E) with function "lightning bolt" and 5E (gene 5 in species 5) with function "moon". Finally, the gene tree shows the evolutionary relationships among the 12 genes from the 5 species. Six gene evolution events are noted on the species tree with roman numerals. Match each of the six events with the type of event they represent (duplication, neofunctionalization or subfunctionalization). 2 Event ii 1 Event vi 3 Event v 2 Event iv 1 Event i 1 Event iii 1. Duplication event 2. Neofunctionalization 3. Subfunctionalization
