Genetics:
The blueprints of our body. Genetics is a study about genes, gene variants, heredity. Genetics explains traits in the human body through presence or absence of a nucleotide sequence of a DNA.
Examples: A person having blue eyes, someone having long legs, someone having dark skin.
Epigenetics:
Factors that control how our genes are expressed. It is the study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself. Environmental influences, such as a person’s diet and exposure to pollutants, can also impact the epigenome
Examples: A person is genetically not predisposed to lung cancer but due to smoking that person may get cancer. Someone not genetically suited to build muscles, due to exercise, diet and conditioning , one may build a decent body.
