Cat coat genetics basic pattern of stripes that underlies the coat. The basic wild-type tabby gene, "Mc", produces what is called a "mackerel striped" tabby (stripes look like thin fishbones and may break up into bars or spots), while a recessive mutant, "mc", produces a blotched or "classic" tabby pattern (broad bands, whorls, and spirals of dark color on pale background usually with bulls-eye or oyster pattern on flank). The classic tabby is most common in Iran, Great Britain and in lands that were once part of the British Empire and Persian Empire. The gene responsible for this differential patterning has been identified
Spotted sand-diver Spotted sand-diver The spotted sand-diver ("Trichonotus setiger") is a perciform fish in the family Trichonotidae. "T. setiger" is the type species of genus "Trichonotus". Spotted sand-divers reach a maximum length of . They have 39 to 41 soft dorsal spines. Males can be distinguished from females by their long dorsal fin rays and larger size. "T. setiger" can be found from the Persian Gulf to Queensland and Melanesia Spotted sand-divers occur in large groups where there are steep sand slopes. They hover above clean sandy substrates and dive into the sand when disturbed. The habiata ususally contains some silt. They
