A longy white Manx female. Although tail suppression (or tail length variety) is not the sole characteristic feature of the breed, [5] the chief defining one of the Manx cat is its absence of a tail to having a tail of long length, or tail of any length between the two extremes. [23]
Cats with the homozygous genotype (MM) die before birth, and stillborn kittens show gross abnormalities of the central nervous system. [3] Cats with the heterozygous genotype (Mm) show severely shortened tail length, ranging from taillessness to a partial, stumpy tail. [3] Some Manx cats die before 12 months old and exhibit skeletal and organ ...
The main strength of the tail suspension test is its predictive validity– performance on the test can be altered by drugs that improve depressive symptoms in people. Specifically, if antidepressant agents are administered before the test, the animal will struggle for a longer period of time than if not and exhibit more escape behaviors. [1]
Another example of a recessive lethal allele occurs in the Manx cat. Manx cats possess a heterozygous mutation resulting in a shortened or missing tail. Crosses of two heterozygous Manx cats result in two-thirds of surviving offspring displaying the heterozygous shortened tail phenotype, and one-third of surviving offspring of normal tail ...
Mental Floss shared this interesting fact, which has to do with the breed's origin, "People once said the Manx was running late for Noah’s Ark, and Noah slammed the door and severed its tail ...

The Mekong Bobtail—a colorpoint cat breed with a bobbed tail. More than one gene is responsible for tail suppression in cats; research is incomplete, but it is known that the Japanese Bobtail and related breeds have a different mutation from that found in the Manx and its derivatives. American Bobtail
