The ghost in our genes: legal and ethical implications of epigenetics
Abstract
Epigenetics is one of the most scientifically important, and legally and ethically significant, cutting-edge subjects of scientific discovery. Epigenetics link environmental and genetic influences on the traits and characteristics of an individual, and new discoveries reveal that a large range of environmental, dietary, behavioral, and medical experiences can significantly affect the future development and health of an individual and their offspring. This article describes and analyzes the ethical and legal implications of these new scientific findings.

Epigenetic Mechanisms of Gene Regulation 1 (Vincenzo E. A. Russo, Robert A. Martienssen & Arthur D. Riggs eds., 1996). DNA consists of a sequence of four different DNA bases or “nucleotides” that consist of adenine (A), thymine (T), guanine (G), and cytosine (C). The order of these nucleotides in a specific functional stretch of DNA called a gene conveys the informational content of DNA. In the DNA double helix, which consists of two parallel strands of DNA bound together in a coiled spiral, C’s always bind with G’s on the complementary strand, and A’s bind with T’s.
