question 34

Essay

You are studying the source of a new virus that has recently infected humans. You suspect that the virus was transferred from other primates (they exhibit a similar infection), specifically, chimpanzees, gorillas, or orangutans. You sample blood from several infected humans and sequence some viral genes. You then build a phylogenetic tree with the human sequences and all the known strains from each primate. Draw a hypothetical phylogenetic tree that would suggest that the virus came from gorillas and that this transfer occurred twice independently. Label chimpanzee sequences (c), gorilla (g), orangutans (o), and humans (h).
