I noticed the other day on wikipedia about a reintroduction of a tiger from Twycross zoo to India in the 1970s. Interestingly, the population of the national park she was released in now have certain phenotypical features of Amur tigers. I didn't realise we'd (or more specifically, Twycross) already done some damage with the old dodgy 'bengals'....:
"Tara, a hand-reared supposedly Bengal tigress acquired from Twycross Zoo in England in July 1976 was trained by Billy Arjan Singh and reintroduced to the wild in Dudhwa National Park, India with the permission of India’s then Prime Minister Indira Gandhi in an attempt to prove the experts wrong that zoo bred hand reared Tigers can ever be released in the wild with success. In the 1990s, some tigers from Dhudhwa were observed which had the typical appearance of Siberian tigers: white complexion, pale fur, large head and wide stripes. With recent advances in science it was subsequently found that Siberian Tigers genes have polluted the otherwise pure Bengal Tiger gene pool of Dudhwa National Park. It was proved later that Twycross Zoo had been irresponsible and maintained no breeding records and had given India a hybrid Siberian-Bengal Tigress instead, although at the time, and taking into account information received regarding all of the tigers kept at Twycross Zoo, it was believed that Tara was a pure Bengal tiger at that time. Dudhwa tigers constitute about 1% of India's total wild population, but the possibility exists of this genetic pollution spreading to other tiger groups, at its worst, this could jeopardize the Bengal tiger as a distinct subspecies"
