According to modern synthetic theory of evolution proposed by Dobzhansky ,all of the following are causes of genetic variability except

Assertion : Grographical isolation brings about sympatric speciation. Reason : Reproductive isolation brings about allopatric speciation.

Choose the correct sequence of evolutionary events in one form of allopatric speciation, using the codes given below : (i) Geographical isolation (ii) Ecological isolation (iii) Increased pre-mating reproductive isolation (iv) Increased genetic divergence (v) Selection completed
