Question

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

Answer 1

When a population is small, the scope and number of variations is limited, diversity and traits are reduced. This further reduces the chances of survival in the event of a disease or geographical disaster. If they all die out and become extinct, their genes will be lost forever. This is why a small number of surviving tigers is a cause of worry from the point of view of genetics.
