How many Siberian tigers are left in the world?

Answer 1

There are about 500 Siberian tigers currently surviving in the wild, but the effective population accounts for genetic diversity. BBC says that the tiger has a very low diversity, which means that any disease or rare genetic disorders will probably be passed on to the next generation. A more diverse genetic population would increase its chance of survival

and would be able to "cancel out" diseases and disorders with healthy genes.
