WebGenetic isolation and speciation [ edit] A genetic species is a collection of biologically compatible crossbreeding natural populations that are genetically distinct from genetically related populations. The Genetic species concept, in contrast to the biological species concept, emphasizes genetic isolation rather than reproductive separation.

One reproductive isolation mechanism may not completely block gene flow, but a combination can effectively separate the gene pool of a species. There are various types of reproductive ...
