Siberian tigers receive DNA test to prevent 'intermarriage' (1/6)

Photo taken on Nov. 19, 2012 shows Siberian tigers at the Siberian Tiger Park in Harbin, capital of northeast China's Heilongjiang Province. The Siberian Tiger Park, world's largest artificially Siberian tigers breeding base, announced that its 1,067 Siberian tigers had all received DNA test. The park began to use DNA tests to prevent "intermarriage" among Siberian tigers in 2001. Siberian tigers, otherwise known as Amur or Manchurian tigers, mainly live in east Russia, northeast China and northern part of the Korean Peninsula. Some 500 of the animals currently live in the wild, with an estimated 12 in Heilongjiang and eight to 10 in neighboring Jilin Province. (Xinhua/Wang Jianwei)
