In the grass species Anthoxanthum odoratum, some of these plants live
Ray Of Light [21]

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.
