The disappearing blonde gene refers to false reports that a scientific study had estimated that natural blonds would become extinct, which were reported as fact in reputable media such as the BBC and the Sunday Times between 2002 and 2006. Claims that blond hair would disappear have been made since 1865.〔 Cites ''Chamber's journal of popular literature, science and arts By William Chambers, Robert Chambers, 1865 (p. 408)'', as well as newspaper mentions from 1890, 1906, and 1961. 1906 reference relates to a newspaper report on a lecture by Major C. E. Woodruff called ''The Disappearance of Blond Types from the American Population'', mentioned in MacCurdy GG, Anthropology At The New York Meeting, Science, 26 April 1907: 653-665 〕 According to the erroneous reports, the World Health Organization, or other experts, published a report claiming that people with blond hair "will become extinct by 2202". The story about the report was a hoax—neither the WHO nor any reputable expert has issued such a report. Those who commented on this alleged report were asked by the WHO to retract.〔(A corrected version of "Cavegirls were first blondes to have fun" ) by ''Sunday Times'', February 26, 2006〕 The extinction claim is based on a misinterpretation of recessiveness in genetics. In reality, unless blond genes are positively selected against, blondeness will not disappear.〔 ("Blondes 'to die out in 200 years'" ), from the BBC, September 27, 2002. 〕 ==In the media== In 2002 BBC News reported that unnamed German experts had concluded that the natural distribution of blond hair would cease within the span of 200 years owing to the genes associated with blond hair being recessive. The article reported the scientists had said that there is a reportedly low number of people carrying the recessive blond allele, especially in nations of mixed heritage (for example, the United States, Canada, Argentina, Brazil, New Zealand and Australia). The dominant alleles (brown hair, black hair, brown eyes) "overthrow" the recessive genes or metaphorically, endanger them. Subsequently the study was attributed to the World Health Organization. In the BBC article Prof. Jonathan Rees of the University of Edinburgh cast doubt on the story—he was quoted as saying "The frequency of blondes may drop but they won't disappear."〔 In October 2002 ''The New York Times'' reported that the World Health Organization had no knowledge of this study.〔 ("Hair-raising story about blonds cut short" ), from ''The Age'', October 3, 2002〕〔(WHO clarification ) 〕 In 2006 the hoax was mentioned by'' The Sunday Times'' when reporting on the publication of a hypothesis of the origins of blonde hair〔 (Cavegirls were first blonds to have fun. ) The online version was corrected later.〕 and ''La Repubblica'': "According to the WHO study, the last natural blond is likely to be born in Finland during 2202." It once again traveled quickly across the World Wide Web.〔 ("Natural blondes are likely to be extinct within 200 years" ) from ''Bit of News''〕 The hoax has also been featured on the "Threat-Down" segment of the satirical television show ''The Colbert Report'' on March 6, 2006, where Stephen Colbert suggested a selective breeding program to save blonds. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Disappearing blonde gene」の詳細全文を読む スポンサード リンク
