Many things. Just physical differences, a mouse is not going to breed with an elephant. Behavioral difference, such as mating dances, calls and the like. Temporal differences, such as one organism is diurnal and the other is nocturnal, or seasonal differences. These are called prezygotic barriers to reproduction.
Postzygotic barriers can be as simple as a sterile match, such as horses and donkeys.
Then there is just physical barriers, such as mountains and water barriers.

What terms refers to one or more populations whose members are capable of interbreeding?
If animals can breed and produce a viable (fertile) offspring they are termed a "species". Often two closely related species can inter-breed and produce an offspring that will be a non-viable (sterile) hybrid. An example of the later would be the cross-breeding of a horse with a donkey.This cross produces a "Mule", which is sterile & unable to reproduce.
These are groups of reproducing populations that are isolated from other groups?
the answer is SPECIES BECAUSE the common definition is that of a group of organisms capable of interbreeding and producing fertile offspring of both genders, and separated from other such groups with which interbreeding does not (normally) happen. Other definitions may focus on similarity of DNA or morphology.
What is an example of postzygotic isolation?
a) Offspring of two individuals of interbreeding species die early
What is the difference between inbreeding and interbreeding?
Interbreeding most commonly refers to breeding two different species within the same genus to get a hybrid. An example of this is breeding a male donkey and a female horse to get a mule.Inbreeding refers to the breeding of two organisms who are related to one another.
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.
Why do geographic isolation cause speciation?
It prevents the two populations from interbreeding. :) -Apex-
When does behavioral isolation occurs?
when two populations are capable of interbreeding but have differences in courtship rituals.
What kind of isolation occurs when two populations are capable of interbreeding but have differences in courtship rituals or other types of behavior?
This type of isolation is called behavioral isolation. It occurs when individuals from different populations are unable to mate because their courtship rituals, behaviors, or other communication methods are incompatible. This can prevent gene flow between the populations and contribute to reproductive isolation.
Why does geographic isolation cause specilation?
It prevents the two populations from interbreeding - APEX
When does behavior occur?
when two populations are capable of interbreeding but have differences in courtship rituals.
Explain why individuals in population a stop seeing individual from population b as potential partners?
This will happen if the two populations diverge genetically so that either their appearance or their behaviour changes. Once differences have built up which prevent interbreeding the two populations have become two different species.
20000 years ago two populations of the black-tailed rats became separated from each other thus preventing their interbreeding The condition described is?
selective breeding.
Two factors that keep populations stable?
Birth and death.
The geographic isolation of two populations of a species tends to increase differences between their gene pools because it?
Prevents interbreeding, therefore allows the development of diverging traits without being balanced by mating with the other population.
What is a genetic pool?
A gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. Thus the actively interbreeding population of a species is a genetic pool comprising the genes for that species. Should something happen that would separate the breeding population into two populations where the populations could not longer mingle to interbreed, there would now be two genetic pools.

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.
