(Following up Question 1.) To understand the evolution of the vge genes, you constructed a phylogenetic tree, showing on the right. Based on the inferred tree, which of the following statements is the likely scenario for vge evolution? Sp. A Sp. C Sp. B Sp. D O The origin of the vge-B gene is likely the result of a gene duplication event O When compared among species A, B, and C, the veg-C gene can be seen as a synapomorphy. O The appearance of vge-B gene is likely during time period (1) O The appearance of vge-C gene is likely during time period (2) O All of the above

You are exploring the Amazon rainforests before it was completely destroyed. Particularly, you focus on a family of plants that are known to produce chemicals with great medicinal benefit. You sequenced the genomes of several related species and identified the gene, vge (à very good enzymea) responsible for the production of a potential anticancer drug. On the right is the schematic of the genomic region where the vge genes resides. You found that different species have different number of the vge genes. For example, the genome of spécies A (Sp. A) carries three copies of vge genes (vge-A, vge-B, and vge-C). Although they all encode the VGE enzyme and have the same function, their DNA sequences are not entirely identical to each other. Based on this observation, you can conclude that vge-A and vge-B are O orthologous to each other O paralogous to each other O analogous to each other O monophyletic to each other O None of the above Sp.
