For many years, this has been a page focused on the genetics of ear lobes. For some people, the ear lobes are connected directly to the side of their head, all the way to the bottom of the lobe. We will refer to those as attached ear lobes. I have attached ear lobes.

For other people, the ear lobe hangs down beyond the point of attachment. We will refer to those as free ear lobes.

At the time I originally wrote this, this trait was considered to be controlled by a single gene. Now we think that there is more involved.

This is not an article about the pros and cons of genetically modified organisms. I am not arguing for them or against them. Instead, the goal of this article is to help you learn some of the basic science involved, to make it easier for you to fact check articles on this topic.
