Have you ever been told that you have a doppelgänger? You and this person may have more in common than physical appearance, as a new study suggests that people who share similar physical traits may have similar DNA.
The authors of the study, published in Cell Reports, compared the appearance of twins, lifestyle and genetic material. They found that similar DNA can bind people in both behavior and appearance.
Using facial recognition algorithms, the researchers identified the most accurate pairs of twins. They then asked the participants to fill out a questionnaire on biometrics, lifestyle, and collected saliva DNA samples.
This data allowed them to compare the similarities of doppelgangers across their genomes, epigenomes, and even microbiomes to see how their composition might affect a person’s appearance.
The results of the study showed that the twins have similar genotypes, but show differences in DNA methylation and microbiomes....<<<Read More>>>...
