Consider the figures below. The species tree shows the phylogenetic relationships for 6 mammal species. The figure next to it shows different genes (the boxes) arranged on a chromosome. The capital letters (A, B, C, D) show the different functions of each gene. The numbers above each box show the gene names. For example, deer have gene 2 with function A and gene 3 with function B. The gene tree at the bottom shows the evolutionary relationships among the 14 genes from the 6 species. Four nodes are circled and labelled with a lower-case letter. The genes and the gene tree are color-coded to be more visually similar to the example we discussed in lecture. Q1) Six gene evolution events are noted on the species tree with roman numerals (i, ii, iii, iv, v, vi). Match each of the six events with the type of event they represent (duplication, neofunctionalization, subfunctionalization). Q2) Look at the four circled nodes labelled with lower-case letters (a, b, c, d). Did a gene duplication event or a speciation event happen at each node?
