Studying a specific type of genetic variation in the DNA sequences of wolves and domestic dogs - called Single Nucleotide Polymorphisms (SNPs)- the scientists identified the transfer of dog gene variants into wolf genomes.

«We found that while hybridisation has not compromised the genetic distinctiveness of wolf populations, a large number of wild wolves in Eurasia carry a small proportion of gene variants derived from dogs, leading to the ambiguity of how we define genetically «pure wolves».
