Theoretical Genetics

Genetics is the study of heredity or the study of how traits are passed from parents to offspring. This study is largely based on genes. Genes are structures found in every single cell that contain information about traits that an organism has or carries.

Epigenetics is the study of heritable changes in gene expression (active versus inactive genes) that do not involve changes to the underlying DNA sequence — a change in phenotype without a change in genotype — which in turn affects how cells read the genes. Epigenetics is the study of inherited changes in gene expression... changes that are inherited, but aren't inherent to our DNA. For instance, life experiences, which aren’t directly coded in human DNA, can actually be passed on to children. Studies have shown that survivors of traumatic events may have effects in subsequent generations.
