Why does geographic isolation cause speciation (Apex)?
it prevents gene flow between populations
The situation of populations by barriers such as rivers mountains or bodies of water is called what?
Populations can become geographically isolated by barriers such as mountains or rivers. These barriers reproductively isolate the populations by restricting or preventing gene flow between them, leading to genetic divergence. Other kinds of geographic features, such as roads, canals, and even agricultural fields can have similar effects.
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.
How are speciation and microevolution different?
Evolution and speciation. ( microevolution is imprecise ) Alleles can change over time in a population of organisms without any great change in the phenotype or behavior of a species. Then, to keep it simple, a geographic barrier arises between portions of the population and they can no longer interbreed, Mutations happen in the separate populations and evolution can take two different paths now with natural selection driving the winnowing of variations so that adaptive change is happening in the immediate environment of the sundered populations. Given enough time the two populations gene pools will have such a variance in the alleles contained in those two gene pools that two different species will arise.
Why is it important to isolate and clone diseased gene?
Scientist must isolate and clone diseased genes in order to study them. A clone of the gene allows scientist to find an exact cure.

How do you isolate the gene in genetic engineering?
You isolate the gene in genetic engineering by first locating the gene you wish to be isolated. Then you use a restrictive enzyme to isolate it, and lastly take the gene out

Why does geographic isolation cause specilation?
It prevents the two populations from interbreeding - APEX
What type of isolating mechanism was important in the formation of Galapagos finch species?
Geographic IsolationSpeciation in the Galápagos finches occurred by founding of new populations, geographic isolation, gene pool changes, reproductive isolation, and ecological competition.

What hsa to change from generation to generation in an evolving population?
The frequency of the populations alleles. Their gene frequency must change to have evolution.
What is a populations or species gene pool how does it change when an environmental change occurs?
Crissy Briana Neally is truly awesome(: *yeeeaaah!
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.
