epigenesis

Meanings

• noun

  The process by which certain genetic traits are turned on or off, not through changes to the DNA sequence itself, but by external or environmental factors acting upon the gene.

  - "The field of epigenetics has revealed that environmental factors can influence the expression of genes."
  - "Research in epigenetics has shown that experiences in early life can have long-lasting effects on gene expression."
