Is your hair natural black, white, yellow, or brown? These are the genes in the body. The reporter learned from the Chinese Academy of Sciences that a new study by the Beijing Institute of Genomics and scientists from multinational research institutes found that there are more than 100 genes affecting human hair color, which broke the “human hair color mainly consists of several known genes. Determine the original perception of. The research results have recently been published in the international academic journal Nature Genetics.
This is a genome-wide study on the color of human hair based on a multi-ethnic large sample population. It was conducted by researchers from Beijing Genomics Institute of the Chinese Academy of Sciences, King's College London, and Erasmus University in the Netherlands in collaboration with researchers from other countries. In this study, the scientists used a combination of questionnaires and expert evaluations to accurately quantify the hair color of nearly 300,000 people, and analyzed the relationship between more than 8 million genetic loci and hair color, and finally found more than 100 new ones. There is a significant association between the new genetic locus and hair color.
The research's co-first author, researcher Liu Fan of the Beijing Institute of Genomics, Chinese Academy of Sciences, said that this finding has deeply analyzed the heritability of hair color and further revealed the molecular basis of human pigment phenotypic variation. Human hair color prediction based on the new discovery site has higher accuracy, and has higher application value in forensic medicine and other fields. It is possible to accurately predict the hair color of unknown offenders through DNA.
