The first scientific discovery is the epigenetic variation where it describes the deviation in the chemical tags that attach to DNA which affect how genes are read. Theses tags are called epigenetic markings that act as switches that control how genes can be read.

In addition, the variability of a trait is how much that characteristic tends to vary in response to environmental and hereditary influences.
