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.
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. [1] [2] They enjoy swimming, which is a characteristic of tigers, and are very sociable like lions. Notably, ligers typically grow larger than either parent species, unlike tigons. [1] [2] [3]
Hybrid incompatibility is a phenomenon in plants and animals, wherein offspring produced by the mating of two different species or populations have reduced viability and/or are less able to reproduce. Examples of hybrids include mules and ligers from the animal world, and subspecies of the Asian rice crop Oryza sativa from the plant world ...
In addition, the researchers showed that mammal species can only produce viable hybrids up to two or three million years after speciation. Wilson et al. (1974) proposes two hypotheses to explain the relatively faster evolution of hybrid inviability in mammals: the Regulatory and the Immunological Hypotheses. Subsequent research finds support ...
For a hybrid form to persist, it must be able to exploit the available resources better than either parent species, which, in most cases, it will have to compete with.For example: while grizzly bears and polar bears may be able to mate and produce offspring, a grizzly–polar bear hybrid is apparently less- suited in either of the parents' ecological niches than the original parent species ...
