geographic isolation.
Sympatric Speciation develops within the range of the parent population. This type of speciation does not include geographical isolation, and can occur rapidly if a genetic change results in a barrier between the mutants and the parent population.
Geographic isolation Low geneflow.

geographic isolation and the reduction of gene flow
It prevents the two populations from interbreeding. :) -Apex-
Geographic isolation as a mechanism for reproductive isolation. In sympatric speciation, new species arise within the same geographic area without physical barriers separating populations. This process typically involves ecological, behavioral, or genetic factors leading to reproductive isolation within a single population.
That would be geographic isolation and reproductive isolation. Both could lead to speciation.
Both sympatric and allopatric speciation involve the formation of new species through the genetic isolation of populations. In both cases, reproductive barriers develop that prevent gene flow between populations, leading to divergence and eventually the formation of separate species. The key difference between the two is that sympatric speciation occurs within the same geographic area, while allopatric speciation involves speciation due to geographic isolation.
Geographic isolation causes the environments to separate. The members of each side will be separated and gradually become more and more distinct as time goes. Eventually, when they are unable to interbreed, that is evidence of speciation.
Allopactric ( other country ) speciation.
Specation can be used in many ways.
