2.1 This chapter is intended to serve as a basic primer on genetics and human health, to provide the scientific background for this Report.[1] Among other things, the chapter describes the emerging understanding of genetic science in the wake of the Human Genome Project, including: the nature of DNA, RNA, genes and chromosomes; patterns of inheritance of genetic traits; the interplay among genes and between genetics and the environment; and the implications of the ‘New Genetics’ for human health.

[1] Chapter 2 of IP 26 also contained a genetics primer to assist public understanding of the issues involved in this Inquiry.
