Reproductive isolation prevents variations from spreading throughout the entire population. Since genetic variations basically occur randomly, the chances that the same variations will occur in both reproductively separated subpopulations are vanishingly slim. Thus, genetic divergence between both subpopulations will occur, and this may eventually lead to speciation.
Isolation stops populations of the same species from interbreeding. This results in separate breeding among populations and genetic differences become more pronounced with each generation.

Polyploid speciation is perhaps the fastest form of speciation because it results in immediate?
reproductive isolation
Which increase speciation?
Geographic isolation Low geneflow.
How are spec spec creation and reproductive isolation related?
How are speciation and reproductive isolation relator
Why does geographic isolation cause speciation (Apex)?
it prevents gene flow between populations
What are three ways that can lead to speciation?
by natural selection, genetic drift and geographical isolation
Speciation that results from geographical isolation that leads to reproductive isolation?
Allopactric ( other country ) speciation.
What is necessary for speciation to occur?
Isolation Is necessary for speciation to occur.
Complete reproduction isolation is evidence that what has occurred?
speciation
How is speciation and reproductive isolation related?
Reproductive isolation is a type of speciation. Reproductive isolation is when a species divides forming two subspecies, due to different mating periods.
Allopatric speciation requires?
geographic isolation.
Polyploid speciation is perhaps the fastest form of speciation because it results in immediate?
reproductive isolation
Speciation without geographic isolation is called what?
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.
Sympatric speciation specifically excludes?
Geographic Isolation
Which increase speciation?
Geographic isolation Low geneflow.
How are spec spec creation and reproductive isolation related?
How are speciation and reproductive isolation relator
What are the two main types of isolation?
That would be geographic isolation and reproductive isolation. Both could lead to speciation.
What is the is the first step in allopatric speciation?
physical isolation of two populations
