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, or the transfer of genes between populations through individuals mating with individuals from another population, helps to keep neighboring populations genetically similar. This process can prevent genetic differentiation and maintain a shared gene pool within a geographic region.

Gene flow is a concept best used to describe an exchange between what?
populations

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?
Genetic diversity decreases, which can lead to reduced adaptability and resilience to environmental changes, higher risk of inbreeding and genetic disorders, and potentially increased vulnerability to diseases and other threats. Additionally, the chances of recolonization and gene flow between populations are diminished, further limiting the species' ability to recover.
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?
Without knowing the specific scenario or event you are referring to, it is difficult to provide an accurate answer. However, in general, any changes or events that affect one population could have ripple effects on another population, depending on the nature of the impact. It's important to consider the interconnections and relationships between the two populations to understand the potential consequences.
