Tabby cat or Sp/Sp together with Mc/mc and Mc/Mc and A/a and A/A. The Ticked tabby pattern is on a different gene locus than the Mackerel and Classic tabby patterns, and is epistatic to the other patterns. A dominant mutation, "T / t", masks any other tabby pattern, producing a non-patterned, or agouti tabby, with virtually no stripes or bars. If the Ticked tabby pattern gene is present, any other tabby pattern is masked. Cats homozygous for the ticked allele ("T / T") have less barring than cats heterozygous for the ticked allele. When a cat of this genetic make-up is selectively
Cat body-type mutation from Treker's dominant mutation. Most teacup and toy size Persian kittens raised now are descendants from Silver and Golden color division to reduce cat size and are in no way related to Treker. Cat body-type mutation Cats, like all living organisms, occasionally have mutations that affect their body type. Sometimes, these cat body-type mutations are striking enough that humans select for and perpetuate them. This is not always in the best interests of the cat, as many of these mutations are harmful; some are even lethal in their homozygous form. This page gives a selection of cat body type mutant
