However, when hybrids are produced between both species, the gene flow between the two will continue to be impeded as the hybrid males are sterile. Also, and in contrast with the great vigor shown by the sterile males, the descendants of the backcrosses of the hybrid females with the parent species are weak and notoriously non-viable.
The liliger is the hybrid offspring of a male lion (Panthera leo) and a female liger (Panthera leo♂ × Panthera tigris♀). Thus, it is a second generation hybrid. In accordance with Haldane's rule, male tigons and ligers are sterile, but female ligers and tigons can produce cubs.
Tiger bone glue is the prevailing tiger product purchased for medicinal purposes in Hanoi and Ho Chi Minh City. [188] "Tiger farm" facilities in China and Southeast Asia breed tigers for their parts, but these appear to make the threat to wild populations worse by increasing the demand for tiger products.

The history of lion–tiger hybrids dates to at least the early 19th century in India. In 1798, Étienne Geoffroy Saint-Hilaire (1772–1844) made a colour plate of the offspring of a lion and a tiger. The name "liger", a portmanteau of lion and tiger, was coined by the 1930s. [4] "Ligress" is used to refer to a female liger, on the model of ...
Ligers and tigons (crosses between a lion and a tiger) and other Panthera hybrids such as the lijagulep. Species P. tigris. A hybrid between a Bengal tiger and a Siberian tiger is an example of an intra-specific hybrid. Family Canidae. Fertile canid hybrids occur between coyotes, wolves, dingoes, jackals and domestic dogs.
The tiger trout (Salmo trutta × Salvelinus fontinalis) is a sterile, intergeneric hybrid of the brown trout (Salmo trutta) and the brook trout (Salvelinus fontinalis). Pronounced vermiculations in the fish's patterning gave rise to its name, evoking the stripes of a tiger .
Since ligers are usually sterile and artificially bred, they would not be considered a part of a natural "evolutionary tree." Probably the best we could do is to put them somewhere in genus panthera, but not as a species. Similarly, the mule is not regarded as a species but as a hybrid. --InformationalAnarchist 7 July 2005 19:27 (UTC)
A white tiger, named Scarlett O'Hara, who was Tony's sister, was cross-eyed only on the right side. A male tiger named 'Cheytan', a son of Bhim and Sumita who was born at the Cincinnati Zoo, died at the San Antonio Zoo in 1992, from anaesthesia complications during root canal therapy. It appears that white tigers also react strangely to ...
