Gene flow between two groups of the same population tends to stabilize alleles, or one way gene flow tends to not change allele frequency enough for speciation. The only speciation driver we know of is natural selection working on two allopatic species separately. Different populations, due to this geographic separation, can speciated, but gene flow between them, whatever the direction, will tend to bring things to a stability, or to a situation that is not enough for speciation.

Which increase speciation?
Geographic isolation Low geneflow.
What is the most important factor that holds a gene pool together and prevents speciation?
gene flow
Why does geographic isolation cause speciation (Apex)?
it prevents gene flow between populations

How would this impact the two populations?
Gene flow would increase between the two halves, and speciation would not occur
Speciation caused by the break of the continents would be by A. parapatry B. gene flow C. allopatry D. sympatry?
C. allopatry
The population of mine was a split knife by river before speciation is completed the two has a rejoined when a drought causes the river to run dry how this impacts the two population?
the gene flow would increase (apex)orGene flow would increase between the two halves, and speciation would not occur.
Does a rugged mountain terrain have a high or low rate of speciation?
A rugged mountain terrain would have a high rate of speciation because mountain would prevent organisms from interacting; hence, gene flow would stop.
How does the size of a gene pool effect speciation?
its not
What kind of selection can result in speciation?
Natural selection seems to be the only selection that can drive speciation with powerful adaptive change. Sexual selection seems to stay within the species and both gene flow and genetic drift do not seem to drive speciation very well.
Why does flow prevent speciation?
