Cat coat genetics as "transmembrane aminopeptidase Q" ("Taqpep"), which also produces the king cheetah coat variant. Spotted tabbies have their stripes broken up into spots, which may be arranged vertically or horizontally. A 2010 study suggests that spotted is caused by the modification of mackerel stripes, and may cause varying phenotypes such as "broken mackerel" tabbies via multiple loci. The "Ticked" gene, "T / t", produces an "Abyssinian ticked" or non-patterned agouti tabby with the dominant allele, having virtually no stripes or bars. Stripes usually remain to some extent on the face, tail, legs, and sometimes the chest. The dominant ticked tabby allele

Though some fish are sexually mature at in length, even by only about half of females will be ready to reproduce. At , 90% of fish are capable of reproduction. An Atlantic mackerel can live for up to 17 years and attain a length of and a weight of . The Atlantic mackerel is of commercial importance to many Atlantic fisheries, which catch it with purse seines, trawls, gill and trammel nets, and trolling lines. Global annual catch is typically in the range of
