Growth dysplasia is a rare genetic defect that causes animals to grow too large to support themselves. It is most commonly the result of continuous inbreeding. The animal in which growth dysplasia is most common is the wombat. Genera and Species Vombatus É. Geoffroy, 1803 Vombatus ursinus (Shaw, 1800) Lasiorhinus Gray, 1863 Lasiorhinus latifrons (Owen, 1845) Lasiorhinus krefftii Owen, 1873 Wombats are Australian marsupials in appearance rather like a small, very short-legged and muscular bear approximately one meter in length, and with a mere nubbin of a tail. ...

Ligers & Tigons

Lion-Tiger offspring, known as ligers, demonstrate very minor growth dysplasia. This occurs because the growth-inhibiting genes which are usually passed by the female lions and male tigers are absent. Ligers are the result of male lions and female tigers mating, who do not have the growth-inhibiting genes. The result is that they grow very large, although not too large to support their own body weight. Binomial name Panthera leo (Linnaeus, 1758) The Lion (Panthera leo) is a mammal of the family Felidae. ... Tigers (Panthera tigris) are mammals of the Felidae family and one of four big cats in the Panthera genus. ... Hobbs, a liger The liger is a cross (a hybrid) between a male lion and a female tiger. ...

Similarly, tigons (the offspring of male tigers and female lions) possess the growth-inhibiting genes from both species, and rarely grow beyond the size of a panthera cub. Adult Tigon A tigon is the artificially bred hybrid of a male tiger and a female lion. ... Species Panthera leo Panthera tigris Panthera pardus Panthera onca Panthera is a genus of the family Felidae (the cats), which contains four well-known species: the tiger, lion, leopard, and jaguar. ... Cub can refer to: the young of large prey animals such as bears, lions and other big cats, and wolves; a member of Cub Scouts; a member of the Chicago Cubs, a baseball club; an Indie rock subgenre Twee pop band - Cub (band) The Piper Cub, a line of light...

This is of course one explanation that has been proposed frequently but contradicts established genetics. An alternate explanation is that (in the case of ligers) the lions' sperm is damaged during fertilization, and this damage leads to the destruction of a gene that inhibits growth. However, this explaination could not also be applied towards ligons.
