Question 3
Why are the small numbers of surviving tigers a cause of worry from the point of view of genetics?
Since the tiger population is decreasing sharply, the expanse of its genetic pool also gets affected. This has a limiting effect on the variations that can be seen in the genetic makeup of the tigers. This has a serious fall-out. For example- If a disease spreads in the tiger population, it might wipe out its entire population leaving no survivors meaning that the existing tigers would get a slim chance to survive if there is a major outbreak of a disease. It might lead to their complete extinction.
