Generally in the allopactric situation, geographic speciation.
A population of organisms is separated by a geographic barrier erected in their range and then the two parts of this population, which have variant allele frequencies possibly, start to have different types of mutations and are possibly under slightly different selection pressure until the allele frequency of the two populations vary so much that if they meat again the two now separate populations can not interbreed any longer. Thus they define a new species by the biological species concept.

Speciation without geographic isolation is called what?
Sympatric Speciation develops within the range of the parent population. This type of speciation does not include geographical isolation, and can occur rapidly if a genetic change results in a barrier between the mutants and the parent population.
Which of the following shows an example of organisms being classified based on their physiological abilities?
Speciation occurs during the evolutionary development, or phylogeny, of a species. In which of the following situations will speciation occur
What is phyletic speciation?
Divergence
Which of the following can result in instant speciation?
Allopatric speciation and sympatric speciation are two factors. Allopatric speciation occurs when physical barriers are formed, separating the specie. This will cause the specie to evolve at different rates causing a new specie to form. Sympatric speciation is less likely to occur when comparing it to allopatric. In sympatric speciation is no longer physical but generic. For example a mutation in the genetic order of the specie (which does not happen as often as physical barriers), and a different mating preference/season.
Why does polyploidy not cause speciation or even be associated with speciation?
Actually it is.
What is necessary for speciation to occur?
Isolation Is necessary for speciation to occur.
What situations will speciation occur?
Speciation is the process of a new species developing. Speciation can occur from a geographical split in the species, Species can split in the same area if they start depending on different foods.
How long it takes for speciation to occur?
several generations
What type of speciation occur when a plant population becomes reproductively isolated while living with its parent population?
Sympatric Speciation
How did speciation occur in the anoles of the Caribbean?
Specific ecological niches
Speciation without geographic isolation is called what?
Sympatric Speciation develops within the range of the parent population. This type of speciation does not include geographical isolation, and can occur rapidly if a genetic change results in a barrier between the mutants and the parent population.
What effect would a very short generation time such as bacteria have on speciation?
Well they would evolve faster, so speciation would occur faster too
What best describes how long it usually takes for speciation to occur?
species originate through allopatric speciation
Which of the following shows an example of organisms being classified based on their physiological abilities?
Speciation occurs during the evolutionary development, or phylogeny, of a species. In which of the following situations will speciation occur
WHAT can occur only when either interbreeding or the production of fertile offspring is prevented among members of a population?
speciation
What is phyletic speciation?
Divergence
How would this impact the two populations?
Without knowing the specific scenario or event you are referring to, it is difficult to provide an accurate answer. However, in general, any changes or events that affect one population could have ripple effects on another population, depending on the nature of the impact. It's important to consider the interconnections and relationships between the two populations to understand the potential consequences.
