Question: an evolutionary tree is shown below similar genes are represented...

Question details

An evolutionary tree is shown below. Similar genes are represented by boxes. The letters X, Y, and Z 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 Z). For example, the pink Z genes-LO 2ß1, and Ζβ2_ are present in species 2. duplication 1 speciation 2 duplication 2 Za Υβ (a) Which genes are homologs? (b) Which genes are paralogs?
