"Tabby" is not one look, and on this breed the registry is precise about it. 's Standard of Points describes three tabby patterns for the British Shorthair by name: Classic, Mackerel and Spotted. Here is how to tell them apart at a glance, and what is happening genetically underneath.
Classic, Mackerel, Spotted: the field guide
Classic
the marbled look: broad, swirling blotches along the flanks, the pattern old cat books call blotched tabby
Mackerel
in the standard's own framing it "differs from the Classic Tabby Pattern only in the body markings": narrow lines run vertically down the body like fish bones
Spotted
same tabby head markings, body pattern broken into spots, carried well down the legs and onto the belly per the standard
All three come in the breed's color range. So a "blue British Shorthair" is a precise, registry-legal description, not seller's poetry.
The gene behind every tabby
One gene family runs the show. The gene, , switches each growing hair between dark and light bands, and that banding is what tabby patterns organize into swirls, lines or spots. Every cat carries a tabby pattern genetically. On a solid British Blue it is hidden by the state, which is why "ghost markings" sometimes show faintly on solid kittens before the adult coat settles. The pattern layout itself (classic vs mackerel vs spotted) is decided by separate pattern genes; the agouti switch just turns the display on.
The silver tabby: the breed's showpiece version
Put the tabby pattern over a silvery base and you get the silver tabby, the high-contrast version most people picture on this breed. The silver base is the same inhibitor effect as on the golden and silver shaded page. It carries the same honest caveat: no DNA test for silver exists, so "DNA-verified silver tabby" is not a thing a laboratory can print.
Tabby, tipped or smoke? Where the lines run
Three families share the pale-base trick, and listings mix them up. A tabby organizes its color into a pattern. A tipped (shaded) cat carries color only on the hair tips, with no pattern. A smoke is solid-colored at rest, with the pale base flashing only in motion. If you can see stripes, swirls or spots, you are looking at a tabby. If the cat sparkles evenly, tipped. If it is solid until it moves, smoke.
