In asexually reproducing organism, geographical isolation will not be a factor in speciation as it does not require another individual for reproduction. Only one individual is capable of producing next progeny hence geographical isolation will not act barrier.

It will affect the frequency of selection which is essential for survival. For effective selection, the population must consist of an infinitely large number of individuals in the population.

Any change in non-reproductive tissues cannot be passed on to the DNA of the germ-cells. therefore, the traits acquired during life-time of an individual are not inherited.

The different ways in which individual with a particular trait may increase are: Natural selection:- Certain variations give survival advantages to individuals in a population in a changed situation resulting in increase of their population.

Natural selection:- Certain variations give survival advantages to individuals in a population in a changed situation resulting in increase of their population.
Genetic drift: accidents in small population even if they give no survival advantage also lead to increase of certain individuals in population.
Will geographical isolation be a major factor in the speciation of an organism that reproduces asexually? Why or why not?
In asexually reproducing organism, geographical isolation will not be a factor in speciation as it does not require another individual for reproduction. Only one individual is capable of producing next progeny hence geographical isolation will not act barrier.

Factors that would lead to rise of new species are: (i) Migration (ii) Natural selection (iii) Geographical isolation (iv) Mutation.

Why are the small numbers of surviving tigers a cause of worry from the point of view of genetics?
It will affect the frequency of selection which is essential for survival. For effective selection, the population must consist of an infinitely large number of individuals in the population.
