In the attempt to rectify these gene inadequacies in white tigers, they were made to mate with royal Bengal tigers, which would result in heterozygous cubs, which would have high immunization and other characters, the Zoo officials said in a statement.Akanksha and another tigress Namrutha have earlier given birth to three female and two male cubs respectively in 2012. So far a total of nine tiger cubs have been born under the latest mating system. Arignar Anna Zoological Park near here, also called the Vandalur Zoo, is the largest zoo in the country.PTI
