What three types of barriers that can cause populations to become reproductively isolated from each other?
Isolation can be due to behavioral, geographical, or temporal barriers.

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.
Speciation can result when two populations have become?
reproductively isolated. This can occur through various mechanisms such as geographical isolation, temporal isolation, or behavioral differences. Over time, this isolation causes genetic divergence and leads to the formation of new species.
How can populations become reproductively isolated?
Populations can become reproductively isolated through mechanisms such as geographic isolation (resulting in allopatric speciation), behavioral differences (resulting in prezygotic isolation), or genetic changes that lead to incompatibility between individuals (resulting in postzygotic isolation). These barriers prevent gene flow between populations, leading to their divergence and ultimately speciation.
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 must happen for speciation to happen?
A population must be isolated in some way.
What factor can cause to two populations to become reproductively isolated?
Geographic isolation, where physical barriers prevent gene flow between populations, can cause reproductive isolation. This can lead to genetic differences accumulating over time, ultimately resulting in the development of separate species.
What situations will speciation occur?
Speciation can occur when populations of a species become reproductively isolated, preventing gene flow between them. This can happen through geographic isolation, where populations are separated physically, or through mechanisms like behavioral differences or polyploidy leading to reproductive barriers. Over time, these isolated populations can accumulate enough genetic differences to become distinct species.
If two populations have been reproductively isolated and can no longer breed and produce fertile offspring the process of what has occurred?
If two populations of the same species no longer interbreed then their differences will start to become more pronounced and eventually they will become so different that they will be classified as two different sub-species.
What factor caused two populations to become reproductively isolated?
It usually is some sort of physical barrier like an large space between islands.
What process occurs when local units of a population become reproductively isolated from other units?
genetic divergence
What is it called when a population diverges and becomes reproductively isolated?
Speciation
What is one cause of speciation?
One cause of speciation is reproductive isolation or the separation of the population of a species from other populations so that it can change without keep getting mixed with other populations( and therefore becoming identical to other populations).
