A gene can appear to move from one spot in the genome to another, a phenomenon called gene trafficking. How is this related to the death of a gene?

A. When a gene is copied to another part of the genome, the copy at the old location might "die" (disappear)
B. When a gene moves to another part of the genome, it can't survive there so it "dies" (becomes a pseudogene)
C. A deleterious gene might move to a different part of the genome so it does not "die" (undergo purifying selection)


Answer: A. When a gene is copied to another part of the genome, the copy at the old location might "die" (disappear)
