The hybrid born from a male tiger and a female lion is called a tigon.
A tigon combines Panthera tigris, the tiger, with Panthera leo, the lion. Its name follows the parent pairing: the father is a tiger and the mother is a lioness. Tigons may show stripes inherited from the tiger and spots or other features associated with lions.
Tigons are produced only in captivity because tigers and lions generally have separate natural ranges and behaviors. They are distinct from ligers, which have the reverse parentage: a male lion and a female tiger. That distinction is the most common source of confusion in quiz questions.
Tigons are usually no larger than either parent species. This contrasts with ligers, which can grow exceptionally large because of differences in inherited growth-regulating genes. Male tigons are generally sterile, while female hybrids may be fertile in rare cases.
