If two populations have been reproductively isolated and can no longer breed and produce fertile offspring the process of what has occurred?
If two populations of the same species no longer interbreed then their differences will start to become more pronounced and eventually they will become so different that they will be classified as two different sub-species.
When are two species to be reproductively isolated?
When the members of two populations cannot interbreed and produce fertile offspring.
In what situation will speciation occur?
Generally in the allopactric situation, geographic speciation. A population of organisms is separated by a geographic barrier erected in their range and then the two parts of this population, which have variant allele frequencies possibly, start to have different types of mutations and are possibly under slightly different selection pressure until the allele frequency of the two populations vary so much that if they meat again the two now separate populations can not interbreed any longer. Thus they define a new species by the biological species concept.
When two species become so different that they can no longer breed it is called what?
On my worksheet for biology the possible answers for that exact question areinfertilityextinctionisolationselection.hope that narrows it down_____________________________The answer is: isolation.
One species evolve into two species?
A common speciation event is called allopactric speciation. This is the geographic separation of a single species into two populations. Naturally, one could expect statistically different genetic variation to arise in these two populations and the environments may be different also. In any event, these two populations, after time, would be headed down different evolutionary roads.

They are now two different species.
When is speciation is complete?
When the two populations can no longer interbreed.
When speciation complete?
When the two populations can no longer interbreed.
What is the condition in which two populations cannot interbreed called?
isolation
What do you call populations that are close enough to interbreed?
sympatry
What is a group of organisms that can interbreed successfully called?
Populations of the same species can successfully interbreed. Humans are a good example of this happening in the real world.
Does geographic isolation contribute to evolution-?
A geographic barrier eg mountain range, river, ocean, desert, can split a species into two populations which can no longer mix with each other. By splitting up a species into two separate populations a geographic barrier can lead to the formation of a new species. The two separate populations start to develop in isolation from each other. Different mutations will occur in the two populations and natural selection will adapt them to the slightly different conditions in the two areas. Given enough time the two populations will become so different that if they are brought together again they will no longer be able to interbreed ie they will have become two different species. This is called allopatric speciation.

How does reproductive isolation causes speciation?
It reduces gene flow.
When members of two populations cannot interbreed and produce fertile offspring what is it?
They are both considered separate species at the point they can no longer interbreed and produce fertile offspring.
Separation of species or populations so that they cannot interbreed and produce fertile offspring?
reproductive isolation
The island sinks and the population of birds that lived on the island returns to its original habitat. what about these bird populations is true?
The populations will not be able to interbreed because they are different species
