The matter came to light after a DNA test was conducted by Hyderabad-based Centre for Cellular and Molecular Biology (CCMB) on the suggestion of Wildlife Institute of India (WII) to assess genetic diversity and paternity assessment of reintroduced tiger population in Panna.
Accordingly, DNA samples of trans-located tiger cubs were collected and matched with a male tiger (T3), which was introduced after 2009.
"It was (found) that four cubs were not sired by the introduced male T3. However, genetic evidence indicated that they were sired by one of the original and probably still existing Panna tigers," according to a letter by CCMB written to WII, copy of which was accessed through RTI by wild life activist Ajay Dubey.
"Higher authorities should seriously examine this finding and proceed further with thorough research. It will help in conservation of tigers. The government must also order CBI enquiry to probe disappearance of tigers from Panna," Dubey said.
The Madhya Pradesh government had formed a committee to look into incidents of tiger deaths and disappearance in Panna Tiger Reserve (PTR). The findings of the committee revealed that poaching was one of the major reasons behind the decimation of tigers in Panna
As many as 58 tigers have died in the past five years due to poaching, territorial fights and old age in the six big cat habitats in Madhya Pradesh.
