Why are the small number of surviving tigers a cause of worry from the point of view of genetics?

Dear Student,

The small number of tigers that are surviving are a cause of worry because if they all die out then their genes will be lost for forever and so their genes will be not pass on to other generations and we will not be able to see any tigers in future . Small number of tigers means less chances of variation. The variations are important in maintaining the stability of a species by natural selection.
