An evolutionary tree is shown below. Similar genes are represented by boxes. The letters X, Y, and represent different species. Similarly colored genes designate genes present in the same species. Use the hypothetical evolutionary tree below to answer the following three questions. ancestral gene speciation 1 Similarly colored genes designate genes present in the same species (species X, Y, or 2). For example, the pink "Z" genes - Za, ZB, and ZB2- are present in species Z. duplication 1 speciation 2 duplication 2 Ya Za YB (a) Which genes are homologs? (b) Which genes are paralogs? (c) Which genes are orthologs?
