Two populations that have no gene flow between them are likely to?

If there is no gene flow between two populations then they will eventually become genetically distinct, thus forming two separate subspecies.
If this isolation continues for longer still, then the 2 populations become so distinct that if you cross-bred between them, then no viable offspring could be produced. This would mean that they had become two separate species.

What is gene flow?
Gene flow is genes moving between two populations. the transfer of genes from one gene pool to another two populations transferring genes
Which of the following is the most predictable outcome of increased gene flow between two populations?
decreases genetic difference between two populations
Why does geographic isolation cause speciation (Apex)?
it prevents gene flow between populations
The maintenance of Hardy Weinberg equilibrium is encouraged?
when there is no gene flow between different populations
What is caused by gene flow?
When genes are exchanged due to the mixing of populations, the result is gene flow. Genetic drift, along with natural selection, mutation, and migration, is one of the basic mechanisms of evolution.
Genetic differences between populations tend to be reduced by?
Gene flow tends to reduce diffences between populations.
What keeps neighboring populations genetically similar?
Gene Flow Gene flow tends to reduce differences between populations. If it is extensive enough, gene flow can amalgamate neighboring populations into a single population with a common gene pool.

Gene flow is a concept best used to describe an exchange between what?
populations
Which of the following is the most predictable outcome of increased gene flow between two populations?
decreases genetic difference between two populations

The maintenance of Hardy Weinberg equilibrium is encouraged?

The term reproductive isolation mechanism refers to?
a blockage of gene flow between populations
When most populations of a wide ranging amphibian species are lost and the few remaining populations are widely separated you expect to see that?
gene flow between populations is reduced
What is caused by gene flow?
When genes are exchanged due to the mixing of populations, the result is gene flow. Genetic drift, along with natural selection, mutation, and migration, is one of the basic mechanisms of evolution.
Is Natural selection is the only mechanisim whereby evolution occurs?
No, there is genetic drift and gene flow between populations to consider.
How would this impact the two populations?
Gene flow would increase between the two halves, and speciation would not occur
