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.
Male ligers are consequently sterile, while female ligers are not. Ligers and tigons were long thought to be totally sterile. However, in 1943, a fifteen-year-old hybrid between a lion and an island tiger was successfully mated with a lion at the Munich Hellabrunn Zoo .
Male ligers also have the same levels of testosterone ng/dl on average as an adult male lion. In addition, female ligers also attain great size, weighing approximately 700 lb (320 kg) and reaching 10 feet (3.05 m) long on average, but are often fertile" at the end of the section describing the large size, but in the following section, the ...

Guggisberg said ligers and tigons were thought to be invariably sterile. The first hybrid of a hybrid, a cub mothered by a liger, was discovered at the Munich-Hellabrunn Zoo in 1943. [ 15 ] The birth of a second generation of hybrids proved that the biologists were wrong about tigons' and ligers' fertility; it now seems that only male lion ...
The male liger and tigon are both sterile as a mule. Females can be fertile and can produce Ti-ligers or Ti-tiglons. This is true with most hybrids nature for some reason wants to protect itself That may have to do with the X and Y chromosomes, maybe the Y chromosome creates sterility?
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.
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.
