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.
Why does geographic isolation cause speciation (Apex)?
it prevents gene flow between 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.
Two populations that are separated by a mountain range can no longer interbreed to produce fertile offspring this is an example of what speciation?
This is an example of geographic isolation, a type of allopatric speciation where physical barriers prevent gene flow between populations, leading to the accumulation of genetic differences and eventually reproductive isolation.
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

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.
Why does geographic isolation cause speciation (Apex)?
it prevents gene flow between populations
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 is a reduction of gene flow?
Reduction of gene flow refers to the decreased transfer of genetic material between populations, often due to geographic barriers, behavioral differences, or reproductive isolation. This can lead to increased genetic divergence between populations, potentially resulting in speciation. Factors such as habitat fragmentation, climate change, or human activities can contribute to this reduction, impacting biodiversity and ecosystem dynamics.
How is gene flow reduced by various types of isolation?
Geographic isolation physically separates populations, limiting the movement of individuals and therefore gene flow. Behavioral isolation arises when different mating rituals prevent successful reproduction between populations. Temporal isolation occurs when populations reproduce at different times, preventing gene flow between them. Finally, mechanical isolation involves incompatibility of reproductive organs which restricts gene flow.
What 2 types of barriers can isolate population?
Two types of barriers that can isolate populations are geographical barriers and ecological barriers. Geographical barriers, such as mountains, rivers, and oceans, physically separate populations, preventing gene flow. Ecological barriers, like differences in habitat preferences or resource availability, can also lead to isolation by causing populations to adapt to distinct environments, reducing interaction and interbreeding between them.
What type of isolation mechanism was important in the formation of Galapagos finches species?
Geographic IsolationSpeciation in the Galápagos finches occurred by founding of new populations, geographic isolation, gene pool changes, reproductive isolation, and ecological competition.
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 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 another name for geographic isolation?
Another name for geographic isolation is allopatric isolation. This refers to a type of isolation where populations become reproductively isolated due to physical barriers preventing gene flow between them.
