Why are the small numbers of surviving tigers a cause of worry from the point of view of genetics? [3 MARKS]

Each point: 1 Mark

1. Small number of tigers means that fewer variations in terms of genes are available.
2. This means that when these tigers reproduce, there are less chances of producing progeny with some useful variations.
3. Hence, evolutionary perspective and change in environment causes risk of extinction. Thus it is a cause of worry from the point of view of genetics .
