The species of <em>Anthoxanthum odoratum</em> is an example of parapatric species.
- Speciation is a process in which a new species form from the existing species due to reproductive isolation.
- In parapatric speciation there is no barrier between the gene flow between similar species.
- In the parapatric speciation populations are adapted to different ecological conditions although the populations of the related species differ in terms of mutation, and due to the effect of drift.
- But they are connected by the random flow of genes between the neighboring organisms irrespective of the changes in their genetic and physiological form.
