A person’s unrelated lookalike, commonly known as a doppelganger, may actually share genes that affect not only how they appear, but also their behavior.
In a new study, scientists did DNA analysis on 32 sets of virtual twins — people with strong facial similarities — and found they possessed similar genetic variants.
“Our study provides a rare insight into human likeness by showing that people with extreme lookalike faces share common genotypes, whereas they are discordant at the epigenome and microbiome levels,” said senior study author Manel Esteller, of the Josep Carreras Leukaemia Research Institute in Barcelona.
“Genomics clusters them together, and the rest sets them apart,” Esteller explained….
