Just when you think you’ve got a grasp on the whole concept of genetics, something new comes along and completely changes your thoughts. That thing, in this case, is epigenetics. And no, I’m not just making up words. Epigenetics is defined as “The study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself” and it may be more important than your DNA! To break this down, think of yourself as a painting. Your DNA provides the tools to make that painting, like the paints, the brushes, and the general idea of what the painting should look like. The painter is the epigenetic factor. Depending on who the painter is, the picture could look a little different. Maybe they don’t use one of the colors your DNA provides, or maybe they decide to make one part of the painting slightly more pronounced. The overall image is the same, but the details differ, therefore making the painting beautifully unique.
