Answer 1

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

Small populations are at risk of extinction because:

1. Lesser opportunity of finding the mate.
2. Interbreeding that leads to interbreeding depression & degeneration.
3. Increased threat to Survival because of habitat destruction & environmental changes.
4. Fewer recombinations & less variability & hence lesser adaptability to changing environment
