; however, in the late 19th and early 20th centuries, tiglons were more common than ligers.

Tiglons can exhibit characteristics of both parents: they can have both spots from the mother
Mother
A mother, mum, mom, momma, or mama is a woman who has raised a child, given birth to a child, and/or supplied the ovum that grew into a child. Because of the complexity and differences of a mother's social, cultural, and religious definitions and roles, it is challenging to specify a universally...

. Any mane that a male tiglon may have will appear shorter and less noticeable than a lion's mane and is closer in type to the ruff of a male tiger. It is a common misconception that tiglons are smaller than lions or tigers. They do not exceed the size of their parent species because they inherit growth-inhibitory gene
Gene
A gene is a molecular unit of heredity of a living organism. It is a name given to some stretches of DNA and RNA that code for a type of protein or for an RNA chain that has a function in the organism. Living beings depend on genes, as they specify all proteins and functional RNA chains...

s from the lioness mother, but they do not exhibit any kind of dwarfism or miniaturization; they often weigh around 180 kilograms (396.8 lb).

A century ago, tiglons were evidently more common than ligers. Gerald Iles, in At Home in the Zoo (1961), was able to obtain three tiglons for Manchester's Belle Vue Zoo

, but wrote that he had never seen a liger. A number of tiglons are currently being bred in China.

Fertility

In Wild Cats of the World (1975), Guggisberg wrote that ligers and tiglons were long thought to be sterile; in 1943, however, a fifteen-year-old hybrid between a lion and an "Island" tiger was successfully mated with a lion at the Munich Hellabrunn Zoo

At the Alipore Zoo in India, a female tiglon named Rudhrani, born in 1971, was successfully mated to an Asiatic Lion

 named Debabrata. The rare, second generation hybrid was called a litigon . Rudhrani produced seven litigons in her lifetime. Some of these reached impressive sizes—a litigon named Cubanacan (died 1991) weighed at least 363 kilograms (800.3 lb), stood 1.32 metres (4.3 ft) at the shoulder, and was 3.5 metres (11.5 ft) in total length.

Reports also exist of the similar titigon (ˌtaɪˈtaɪɡən), resulting from the cross between a female tiglon and a male tiger. Titigons resemble golden tigers but with less contrast in their markings. A female tiglon born in 1978, named Noelle, shared an enclosure in the Shambala Preserve with a male Siberian Tiger called Anton, due to the keepers' belief that she was sterile. In 1983 Noelle produced a titigon named Nathaniel. As Nathaniel was three-quarters tiger, he had darker stripes than Noelle and vocalized more like a tiger, rather than with the mix of sounds used by his mother. Being only about quarter-lion, Nathaniel did not grow a mane. Nathaniel died of cancer
