AI Visual Phenotype vs. Certified Pedigree Reality
Visual breed identification determines phenotypic resemblance—detecting whether a cat displays the coat color, bone structure, ear geometry, and facial markers associated with the Russian Blue standard. However, an authentic purebred cat can only be certified through official genealogical registration documents (such as TICA or CFA pedigree papers). A cat showing strong Russian Blue characteristics is frequently a magnificent domestic mix inheriting prominent ancestral genes.
