Question

Will geographical isolation be a major factor in the speciation of self pollinating plant species ? Why or why not ?

Answer 1

No, geographical isolation will not be a major factor in the speciation of self-pollinating plant species. Geographical isolation creates the separation of the population. It is because in self-pollinating species, new variants are not formed and they do not show any variation in the population. After self-pollination, homozygous line evolve. In contrast, after cross-pollination, heterozygous line evolve and it results in the variation of traits in the population.
