The liger is a hybrid offspring of a male lion (Panthera leo) and a tigress, or female tiger (Panthera tigris). The liger has parents in the same genus but of different species. The liger is distinct from the opposite hybrid called the tigon (of a male tiger and a lioness), and is the largest of all known extant felines.
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.
Panthera hybrids are typically given a portmanteau name, varying by which species is the sire (male parent) and which is the dam (female parent). For example, a hybrid between a lion and a tigress is a liger, because the lion is the male parent and the tigress is the female parent.
The liger is the offspring of a female tiger and a male lion and the tigon the offspring of a male tiger and a female lion. [45] The lion sire passes on a growth-promoting gene, but the corresponding growth-inhibiting gene from the female tiger is absent, so that ligers grow far larger than either parent species.
Hybrid incompatibility occurs when the offspring of two closely related species are not viable or suffer from infertility. Charles Darwin posited that hybrid incompatibility is not a product of natural selection, stating that the phenomenon is an outcome of the hybridizing species diverging, rather than something that is directly acted upon by selective pressures.

The last tigers were sighted there in 1976. [10] [11] The Javan tiger preyed on Javan rusa (Rusa timorensis), banteng (Bos javanicus), and wild boar (Sus scrofa); and less often on waterfowl and reptiles. Nothing is known about its gestation period or life span in the wild or captivity.
In May 2007, the government of China reported to the CITES secretariat that there is no confirmed presence and declared the goal to reintroduce South China tigers to the wild. [18] In September 2007, a body of an Asian black bear was found in Zhenping County that had possibly been killed and eaten by a South China tiger. In October 2007, a ...
It ranks among the biggest wild cats alive today. It is estimated to have been present in the Indian subcontinent since the Late Pleistocene for about 12,000 to 16,500 years. Its historical range covered the Indus River valley until the early 19th century, almost all of India , western Pakistan , southern Nepal , Bangladesh , Bhutan and ...
