Question: Can you explain the concept of epigenetics and its implications on inherited traits and gene expression?

This question requires an understanding of genetics and how external factors can influence gene expression and be passed on to future generations. It touches on the complex relationship between genetics and the environment, providing an opportunity for an in-depth discussion on the topic.
