geographic isolation, also known as sympatric speciation is:
A mode of speciation occurring as a result of a radical change in the genome of a subpopulation, reproductively isolating the subpopulation from the parent population..
soo basically, for example, a mountain could seperate two species.. so then the species on one side of the mountain will mate with eachtoher, and on the otherside theyll do the same.. so there will also be less gene flow.. and it will have a founder effect ( a small change to a small population ) on the species..How does geographic isolation affect a p opulation over time? Explain.?
An isolated population will undergo ';genetic drift';. The isolated population gradually accumulates genetic change distinct from its parent population. Eventually the two will drift so far apart that they would not be able to interbreed were they to be re-introduced to one another.How does geographic isolation affect a p opulation over time? Explain.?
Allopathy is another term for this effect.
When a species portion becomes separated it may evolve characteristics which differ from the parent species. This would especially be true if there was a small population to begin with and one of the founders had a unique trait (extremely tall, for instance) - also known as the founder effect.
