1. 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.

  5. 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. Genetic drift: accidents in small population even if theyRead more

    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.
    Genetic drift: accidents in small population even if they give no survival advantage also lead to increase of certain individuals in population.
