Any time there's a barrier... physical, geographical (distance), or behavioral... between the two that means they no longer reproduce with each other but only within their own group.

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.

What is it called when a population diverges and becomes reproductively isolated?
Speciation
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 does it mean if 2 populations of a species become isolated?
If two populations of a species become isolated, it means that they are separated from each other and cannot interbreed. Over time, this isolation can lead to genetic differences between the populations, potentially resulting in the development of new species through the process of evolution.
What type of speciation occurred when a plant population becomes reproductively isolated while living with its parent population?
Sympatric Speciation
What happens when members from separated populations do not reproduce with each other?
Over time, the populations may become genetically distinct from one another due to accumulation of different mutations. This can lead to the evolution of new species if the genetic differences become significant enough to prevent successful reproduction between individuals from the two populations.
Speciation can result when two populations have become?
Reproductively Isolated.
What happens when two populations have been reproductively isolated and can no longer breed?
Speciation
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 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.
When are two species to be reproductively isolated?
When the members of two populations cannot interbreed and produce fertile offspring.
How does roproductive isolation relate to evolution?
If two sub-populations of a species become reproductively isolated, it means that adaptation or genetic drift can make the two populations diverge genetically. If, as a result of this divergence, upon reintroduction, members of the two sub-populations no longer reproduce successfully, the two sub-populations have become different species.
What is divergence in relation to evolution?
Increasing divergence between reproductively isolated populations, occasionally leading to speciation, is one effect of evolution.
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 process occurs when local units of a population become reproductively isolated from other units?
genetic divergence
What factor caused two populations to become reproductively isolated?
It usually is some sort of physical barrier like an large space between islands.
What is the law of evolution?
There's no "the" law of evolution.There are various lawS of evolution though. For instance, it is a law of evolution that reproductively isolated populations will always diverge genetically.
Which idea explains Darwin's observations about galapagos Islands finches?
Biological Species Concept, which defines species as groups of interbreeding populations that are reproductively isolated from other groups.
