Multiple Choice

Which statement BEST describes the role and importance of mobile genetic elements in genomes?

• A) Mobile genetic elements almost always have either neutral or deleterious consequences for their host.
• B) Mobile genetic elements are largely beneficial to hosts because they introduce new phenotypic variation into a population via transposition and/or duplication of important genes.
• C) Mobile genetic elements can have deleterious, neutral, OR beneficial consequences for the host organism, and all three kinds of outcomes are common.
• D) Mobile genetic elements are especially important for plant genomes such as the tomato, but they are not present in most animal genomes.
