Epigenetics refers to the modulation of gene expression, due to a variety of environmental and lifestyle-related factors . These changes do not alter the DNA sequence, but rather, how the genes are expressed, which means they can be regulated on or off and also up or down in their intensity. Epigenetics defies the long-standing Darwinian and Mendelian approach to genetics, and instead embraces a quasi- or pseudo-Lamarckian approach to inheritance, focusing on the concept that changes in a person’s methylation pattern can induce profound long term personal changes and maybe, more importantly, transgenerational effects.
