Question

why are the small numbers of surviving tigers a cause of worry from genetic point of view.

Answer 1

Sometimes a species (a type of animal or plant) may completely die out. it may become extinct. Once a species is extinct,its genes are lost for ever. It cannot re-emerge at all. The small numbers of surviving tigers are a cause of worry from the point of view of genetics because if they all die out and become extinct, their genes will be lost for ever. Our coming generations will not be able to see tigers at all.

Answer 2

Why are the small numbers of surviving tigers a cause of worry from genetic point of view?

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
