There’s no objective measure for quantifying similarity. We can measure relative similarity, though—but that scale will vary depending on what it’s relative to.

We could measure genetic similarity relative to a typical unrelated person, or relative to the nearest non-human animal, or relative to the most distantly-related living organism, or relative to random noise. (And you can do the same for facial similarity.)
