Their piercing blue eyes and striking monochrome fur have made white tigers a sought after attraction all over the world.
白虎以其深邃的藍(lán)眼睛和奪目的單色皮毛，成為全世界廣受追捧的奇觀。

Only one in every 10,000 wild tigers are born with leucism.The condition is linked with a series of health problems. Many born in captivity have immune deficiencies and are cross-eyed, while some are born with neurological issues, cleft palates, bulging eyes and other facial deformities.
每一萬頭野生老虎只有一頭是生來就有白化癥。白化癥和一些列健康問題相關(guān)，許多人工飼養(yǎng)的老虎有免疫缺陷、對眼斜視，還有些生來便有顱腦問題、裂腭、凸眼和其他面部缺陷。

Kenny the tiger was just two years old when he was rescued from a private breeder in Arkansas by Turpentine Creek Wildlife Refuge in 2000. Born with a short snout, broad face and teeth jutting out at separate angles, he was being kept in a filthy enclosure as he was not pretty enough to sell. For Kenny, he was lucky enough to live out the last of his days at the animal sanctuary.
2000年，松節(jié)油溪野生動物庇護(hù)所從阿肯色私人育虎員手里救下老虎肯尼時，肯尼才兩歲。生來鼻子短小，臉型寬大，牙齒差互交錯，因為貌丑不好賣，肯尼當(dāng)時就被圈養(yǎng)在骯臟的環(huán)境里。對于肯尼來說，臨終前能在動物庇護(hù)所度過已是萬幸。

An orange Benghal tiger named Willie was also rescued, which had crossed eyes, and was believed to have been Kenny's brother. Both tigers' deformities are thought to have?stemmed?from generations of inbreeding. Another white tiger, Zabu, was left with a permanent 'smile' after she was born with a cleft palate.
另有一只名為威利的橙色孟加拉虎也被救下。威利斗眼斜視，據(jù)悉是肯尼的兄弟。人們認(rèn)為這兩頭老虎的缺陷是因好幾代的近親交配引發(fā)的。另外還有只白虎，名為扎布，生來即裂腭，面部也因而留下永恒的“微笑”。

All white tigers seen today are a result of breeding programs at zoos around the world - often between Bengal and Siberian tigers.
現(xiàn)今世界上所有的白虎都是動物園近親交配項目的結(jié)果，通常是孟加拉虎和西伯利亞虎近親繁殖。

The white coat is a double recessive gene so most of the cubs born through this inbreeding have normal coloring but suffer the same defects such as crossed-eyes and deformities and are referred to in the trade as throw away tigers. Around 80 per cent of white tiger litters are stillborn while those who survive usually have a reduced life span.
白色皮毛是雙隱性性狀基因，所以多數(shù)小老虎通過近親繁殖顏色正常，但都有同樣的缺陷，如斜眼。而生理有缺陷的老虎在行內(nèi)則是要被遺棄的。約八成被遺棄的白虎都夭折了，而存活者則折壽。
