Eddie and Freddy are identical twins who grew up in the same home but then went their separate ways after high school. Eddie moved to the Midwest and became a family farmer. Freddy moved to New York City and became a high-powered attorney. A university research project measures their DNA methylation levels at age 6, age 36, and age 60. Which statement MOST likely reflects the results?

Question

Quizplus · Accepted Answer

Although Eddie and Freddy have identical DNA, their different lifestyles and environments could cause epigenetic changes that affect their DNA methylation levels. Since Eddie is a farmer and lives in the Midwest, he may be exposed to different environmental factors than Freddy, who is an attorney and lives in New York City. Additionally, their different lifestyles and diets could contribute to differences in their methylation levels over time. However, since they are identical twins, their methylation levels at age 6 should be similar. As they age and are exposed to different environments and lifestyles, their methylation levels may diverge.
