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.
Ligers and tigons were long thought to be sterile; in 1943, however, a 15-year-old hybrid between a lion and a tiger was successfully mated at the Munich Hellabrunn Zoo. The female cub was then raised to adulthood. [2] Like the liger, male tigons are sterile while the females are fertile.

Haldane's rule is an observation about the early stage of speciation, formulated in 1922 by the British evolutionary biologist J. B. S. Haldane, that states that if — in a species hybrid — only one sex is inviable or sterile, that sex is more ...
Both male and female reindeer grow antlers. This is a trait that no other species in the deer family possesses. The reason, a peculiar result of circumstances and biological luck, reflects.
In general, most ligers grow more than 3.3 m (10 ft 10 in) in length and weigh more than 400 kg (880 lb). [16] According to the Guinness World Records (through 2013), the world's largest felid was the adult male liger, Hercules, from Myrtle Beach Safari, a wildlife reserve in South Carolina, US. He was measured at 3.33 m (10 ft 11 in) (standing ...
