The tigon is a hybrid offspring of a male tiger (Panthera tigris) and a female lion, or lioness (Panthera leo).[http://scholar.lib.vt.edu/ejournals/SPT/v6n3/lee.html Techné v6n3 – Patenting and Transgenic Organisms: A Philosophical Exploration]. Scholar.lib.vt.edu. Retrieved on 17 September 2013. They exhibit visible characteristics from both parents: they can have both spots from the mother (lions carry genes for spots – lion cubs are spotted and some adults retain faint markings) and stripes from the father. Any mane that a male tigon 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.
Tigons do not exceed the size of their parent species because they inherit growth-inhibitory genes from both parents, but they do not exhibit any kind of dwarfism or miniaturization; they often weigh around {{cvt|180|kg}}. It is distinct from the liger, which is a hybrid of a male lion and a female tiger, often weighing from {{cvt|320|kg}} to {{cvt|550|kg}}. {{fact|date=December 2013}}
Fertility
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.{{Cite book |last=Guggisberg |first=Charles Albert Walter |title=Wild Cats of the World |url=https://archive.org/details/wildcatsofworld00gugg |url-access=registration |year=1975 |publisher=Taplinger Publishing |location=New York |isbn=0795001282}} Like the liger, male tigons are sterile while the females are fertile.
At the Alipore Zoo in India, a tigoness named Rudhrani, born in 1971, was successfully mated to a male 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 weighed at least {{cvt|363|kg}}, stood {{cvt|1.32|m}} at the shoulder, and was {{cvt|3.5|m}} in total length.[http://www.natureasia.com/en/nindia/article/10.1038/nindia.2017.46 The litigon rediscovered]. www.natureasia.com.

Coexistence of parental species

As with the liger, the tigon is found only in captivity, because the habitats of the tiger and lion do not overlap. In the past, however, the Asiatic lion did coexist with the Bengal tiger in the wilderness of India, besides occurring in countries where the Caspian tiger had been, such as Iran and Turkey.Pocock, R.
