WebMar 1, 2024 · Inbreeding 101 Like humans, dogs tend to be 99.8-99.9% genetically similar to other members of their species. Even other species can exhibit similarities—dogs and humans are 64% similar at the base pair level. But genetic variation is the spice of life, and the 0.1-0.2% of the genome that differs encodes a myriad of variation. WebInbreeding is the mating of organisms closely related by ancestry.
