According to a new study published in the "Cell Report" magazine on the 23rd, people with similar faces may have similar DNAs. The study revealed that the strong similarity of the face is related to the common genetic mutation, providing unique insights for the molecular characteristics of the potential facial structure.

"Our research provides a rare opportunity to perceive human similarity," said Marinel Estler, a senior author of Barcelona-Carreras Institute in Barcelona, ​​said because we found that we found that they look very similar to Humans have a common gene type, but they are inconsistent in the level of apparent genomes and microbiological groups. "Genomics allowed them to" gather ", and the rest were distinguished.

Due to the development of Wanwei.com and the possibility of global human photo exchange, the number of virtual twins that has nothing to do with genes has increased on the Internet. In this new study, Estler's team shot random humans with the same facial characteristics at the molecular level.

To this end, they recruited the people behind the works based on the Canadian artist Francois Brunell's photography. Brunell has been shooting globally but completely strangely shot globally since 1999. They got 32 pairs of "twins" avatar photos. Researchers use three different facial recognition algorithms to determine an objective similarity measurement standard.

In addition, the participants completed a comprehensive biological statistics and lifestyle questionnaires, and provided saliva DNA for multi -group analysis. This set of unique sample enables researchers to study how genomics, apparent genome, and microbiology have contributed to human similarity.

The results show that these individuals have similar gene types, but they are different in DNA methylation and microbial group landscapes. Genetic analysis shows that 9 of these 16 pairs of people gather together, based on 19277 common single nucleotide polymorphisms.

In addition, the characteristics of body weight and height, as well as the characteristics of smoking and education are also related to similar matching. In summary, these results show that common genetic mutations are not only related to similar appearances, but also may affect common habits and behaviors.

Although there are small limitations such as samples, these findings may provide molecular basis for applications in various fields such as biomedicine, evolution, and forensic medicine. For example, in the field of forensic medicine, the criminal's face can be rebuilt through DNA; in genetic diagnosis, the genome clues they already have according to the patient's facial photos can be understood.
