Do Your Ears Hang Low?

Caption

A common, hands-on method for teaching genetics in grade school encourages students to compare their earlobes with those of their parents: Are they attached and smoothly mesh with the jawline? Or are they detached and dangly? The answer is meant to teach students about dominant and recessive genes.
