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]
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.
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 ...
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.
Experts still don’t have basic answers as to why human ovaries age two times faster than the rest of their body. Or why humans go through menopause in the first place (a process we share with ...
Male genitalia of Lepidoptera. The main component of the male reproductive system is the testicle, suspended in the body cavity by tracheae and the fat body.The more primitive apterygote insects have a single testis, and in some lepidopterans the two maturing testes are secondarily fused into one structure during the later stages of larval development, although the ducts leading from them ...
Japanese researchers announced last year that healthy fertile mice had been born using eggs created from male mice's tail-tip cells. The male-derived eggs were fertilized with regular sperm, thus ...
