Scientists say they have developed a way to predict a person’s probable hair colour using markers in their DNA. The study paves the way for a forensic test that could estimate the hair colour of a suspect from DNA left at a crime scene.

科學家說,他們已發展出一種方法,可以使用DNA中的標記,來預測人可能的髮色。這份研究為根據犯罪現場遺留的DNA來推測嫌犯髮色的法醫鑑識開啟了坦途。

A Dutch-Polish team of researchers have published details in the journal Human Genetics. The researchers found that it was possible to determine with an accuracy of more than 90% whether a person had red hair, with a similar accuracy for people with black hair They could estimate with an accuracy of more than 80% whether a person’s hair color was blonde or brown.

荷蘭與波蘭研究團隊在人類基因學期刊刊登報告細節。研究人員發現,推斷紅髮者的正確性可超過90%,推測黑髮也有類似的正確性。推測金色或棕色頭髮正確率超過80%。

This new genetic approach is also able to differentiate between some hair colours that are similar, for example, between red and reddish blonde, or between blonde and dark blonde hair.

這種新的基因檢測方式也可以分辨出類似的髮色,舉例來說,紅色與紅帶金色,或是金色與深金色。

The DNA can be taken from blood, sperm, saliva or other samples that would be relevant in forensic case work, say the researchers. Lead scientist Manfred Kayser, from Erasmus University Medical Center in Rotterdam, said:That we are now making it possible to predict different hair colours from DNA represents a major breakthrough because, so far, only red hair colour, which is rare, could be estimated from DNA.

研究人員說,DNA可從血液、精子、唾液等樣本取得,這都與法醫鑑識案件工作有關。領導研究的鹿特丹伊拉斯姆斯大學醫學中心科學家凱瑟表示:我們現在可能從DNA預測不同的髮色,這代表重要的進展,因為目前只有少見的紅髮可從DNA推測出來。
