This occurs by an extreme change in the habitat. A limited separation of members of a population followed by reintroduction back to parent population B. Emergence of a reproductive barrier C.
Allopatric speciation occurs when a group of individuals of a species becomes isolated and differentiates into one or more new species that can no longer reproduce with members of the original group. Continuous gene flow between populations C. It is recommended that you save your response as you complete each question.

Genetic diversity cannot cause speciation as it requires a very large group of individuals to happen so.
Speciation the formation of new and distinct species in the course of evolution. This is a type of allopatric speciation in which the species are not formed by any physical barrier. A limited separation of members of a population followed by reintroduction back into the parent population B.

BIOLOGY 101 - What is required for speciation to occur. Speciation involves the splitting of a single evolutionary lineage into two or more genetically independent lineages.
In eukaryotic speciesthat is those whose cells possess a clearly defined nucleustwo important processes occur during speciation. Though we admit that genetic diversity within a species may cause some variations in a group but as a whole. 12 What must happen for speciation to occur.
