Can Allopatric species mate?

One of the most widely accepted concepts of species is the biological species concept (BSC). According to the BSC, allopatrically formed species are postzygotically isolated, i.e., even when they secondarily come in contact and can interbreed, they are incapable of producing fertile hybrids.

In this way, what is allopatric speciation and give an example?

Allopatric speciation occurs when a population is separated geographically; for example, by an isthmus splitting an ocean or fruit flies being separated in the lab. Then the populations on both sides of the barrier cannot mate with each other, and each population evolves separately.

Secondly, what are 3 ways that speciation can happen? There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another: allopatric, peripatric, parapatric, and sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments.

Correspondingly, why is allopatric speciation most common?

Allopatric speciation, the most common form of speciation, occurs when populations of a species become geographically isolated. Over time, the populations may become genetically different in response to the natural selection imposed by their different environments.

How does allopatric speciation happen?

Allopatric speciation occurs when a new species evolves in geographic isolation from its ancestor. It can happen like this: One species could split into two if a physical barrier, such as a new river, divided its geographic range.
