'''''Genome: The Autobiography of a Species in 23 Chapters''''' is a 1999 [[popular science]] [[book]] by the science writer [[Matt Ridley]], published by Fourth Estate. The chapters are numbered for the pairs of human [[chromosomes]], one pair being the X and Y [[sex chromosome]]s, so the numbering goes up to 22 with Chapter X and Y couched between Chapters 7 and 8.
 
The book was welcomed by critics in journals such as ''[[Nature (journal)|Nature]]'' and newspapers including ''[[The New York Times]]''.<ref name=Kealey/><ref name=Silver/> The ''[[London Review of Books]]'' however found the book "at once instructive and infuriating", as "his right-wing politics lead him to slant the implications of the research".<ref name=Coyne/>

Line 31 ⟶ 32:
;Chapter 2, Species
 
Ridley discusses the history of human kind as a genetically distinct species. He compares the human genome to [[Common chimpanzee|chimpanzee]]s, and ancestral [[primates]]. He also points out that until the 19th Centurycentury, most scholars believed that there were 24 sets of genes, not 23 as known today.

Line 39 ⟶ 40:
;Chapter 4, Fate
 
[[Huntington's Coreachorea]] is used to discuss the use of a particular sequence on [[Chromosome Four]] to cause traumatic health consequences. The search for the chromosomal source of this and other related diseases is discussed through the work of [[Nancy Wexler]], someone who may have inherited the gene but who turns to scientific work to study it in others.
 
;Chapter 5, Environment
Line 72 ⟶ 73:
;Chapter 11, Personality
 
Ridley chooses the gene [[D4DR]] which codes for the manufacture of [[dopamine]] and is located on the short arm of [[chromosome 11]]. Interactions between dopamine, [[serotonin]] and other [[Serotonin|serotonin neurochemistry]] are lightly covered.
 
;Chapter 12, Self-Assembly
Line 104 ⟶ 105:
;Chapter 19, Prevention
 
It might be possible to prevent or cure [[Alzheimer's disease]] and [[coronary heart disease]]. APO genes like APOE influence fat and cholesterol metabolism. The E4 allele of EPOE contributes to the plaque buildup of Alzheimer's. [[Genetic testing]] may help patients take early preventative action.
