Plzz guys ans this.....

Answer 1

Because it does not depend on other plants for it's process of reproduction to be carried out.

Answer 2

Explanation:

• Formation of ‘new species’ from pre-existing population is called ‘speciation’.
• The basic factor involves in speciation of new “self-pollinating” plant species is genetic drift, natural selection, and mutation.
• The factor “geographical isolation” cannot be considered for self-pollination plants because no physical barrier happens in self-pollination plant.
• The self-pollinating plant rarely shows the variation.
• This is because the self-pollinating plant receive the pollen grain from same flower or another flower on another plant.
