Reproductive isolation.

Reproducive isolation.

Reproductive isolating mechanisms :

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

Statement (s ) : Populations of a species inhabiting different geographical areas are in a continuous process of adaptation to their surrounding environments and this leads to the evolution of species. Reason (R ) : Geographical barriers obstruct interbreeding of populations of a species leading to reproductive isolation and evolution of new species.

Assertion : Sympatric species are geographically isolated. Reason : Sympatric species are reproductively isolated.

Asertion: The species is reproductivley isolated natural population. Rerson: Prokaryotes cannot be kept under different species on the basis of reproductive isolated.

Morphologically simillar but reproductively isolated species are called :-

Two species can be said to be reproductively isolated if they are

Closely related, morphologically similar reproductively isolated, sympatric populations are called as

Closely related, morphologically similar reproductively isolated sympatric populations are designated as
