The tigons

when it appers tigreão it is just a mistake in english it is tigon to lazy today.The tigon is a hybrid cross between a female lion and a male tiger. The tigreão is not as common as the liger, however, in the late nineteenth and early twentieth century, were more common tigreões ligres.Podem that exhibit characteristics of both parents: they may have spotted the mother (lions carry genes for spots - lion cubs are spotted) and stripes from father.

The mane of tigon will be shorter and more discreet than the lion and more like the tuft of the tiger. It's a mistake to think that tigreões are smaller than lions or tigers. Do not exceed the size of their parents because they inherit the gene inhibitor of growth of the mother and the father lion tiger but do not present any kind of dwarfism or miniaturization, they often weigh around 180 kg.

The relative rarity of tigons is attributed to the fact the Tigers find the male mating behavior of the lioness too subtle and escape them some clues about her interest in mating. However, lionesses are active and agile in applying for mating, so the current rarity of tigons due to the fact that they are less impressive in size than ligers, lowering the value of novelty. A century ago, the tigreões were more common than ligers. Gerald Iles, in the work At Home In The Zoo (1961) managed to get 3 tigreões to Belle Vue Zoo in Manchester, but wrote that he had never seen a liger. Currently there are a significant number of tigreões to be created at work China.Na Wild Cats Of The World (1975), Guggisberg wrote that ligers as well tigons were sterile, however, in 1943, a hybrid of lion and tiger "Island" with 15 years of age was successfully mated with a lion's Hellabrunn Munich Zoo. The female cub, although of delicate health, he survived to adulthood. The tigreões males are sterile, whereas females are fertile. By the fact that only female ligers and tigreões are fertile, ligers and tigreões can not reproduce with each other. At the Alipore Zoo in India, a female named tigreão Rudhrani, born 1971, was successfully mated to an Asiatic Lion named Debabrata. The rare, second generation hybrid was called a li-li-generated 7 tigreão.Rudhrani tigreões during his lifetime. Some of these reached impressive sizes - a li-tigreão named Cubanacan (died 1991) weighed 363 kg, average height 1.32m at the shoulder and had a 3.5 m total length.

There are also records tigreão ti-, li-ligers and ti-liger resulting from a cross between a tiger and female tigreão male. Ti-tigreões are similar to the Golden Tiger but with less contrast in their stripes. Tigreão a female born in 1978, named Noelle, shared an enclosure in the Shambala Reserve with a male Siberian Tiger called Anton, due to the attendant belief that the female was sterile. In 1983, Noelle had a ti-tigreão named Nathaniel. As Nathaniel was three-quarters tiger, he had darker stripes than the progenitor and vocalized more like a tiger than a mixture of sounds emitted by the mother. Being only about quarter-lion, Nathaniel did not ruff. Nathaniel died of cancer at 8 or 9 years. Noelle also developed cancer and died shortly afterwards.
