In allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation. In sympatric speciation, groups from the same ancestral population evolve into separate species without any geographical separation.

What is an example of sympatric speciation?
An extremely recent example of sympatric speciation may be occurring in the apple maggot fly, Rhagoletis pomonella. Apple maggot flies used to lay their eggs only on the fruit of hawthorn trees, but less than 200 years ago, some apple maggot flies began to lay their eggs on apples instead.
How do allopatric and sympatric speciation differ quizlet?
How do allopatric and sympatric speciation differ? Allopatric speciation involves a physical separation of groups as they form new species; sympatric speciation does not. ... The allopatric case would occur at a much slower rate than the sympatric case involving allopolyploid offspring.
What does sympatric mean?
Sympatry is the term used to describe populations, varieties, or species that occur in the same place at the same time.
What is needed for sympatric speciation?
Sympatric speciation occurs when populations of a species that share the same habitat become reproductively isolated from each other. ... For a tetraploidy animal to reproduce, it must find another animal of the same species but of opposite sex that has also randomly undergone polyploidy.
What is and give an example of allopatric speciation and sympatric speciation?
Explanation: Allopatric speciation occurs when a geographical barrier, like a river, mountain, or canyon, separates members of a population. ... The example with the hawks refers to sympatric speciation, where no geographical barrier exists, but speciation can still occur due to other stressors.
What would be expected to lead to allopatric speciation?
Which would be expected to lead to allopatric speciation? ... The allopatric case would occur at a much slower rate than the sympatric case involving allopolyploid offspring.
How might reproductive barriers arise in allopatric speciation?
Allopatric (“Other Country") Speciation Allopatric speciation occurs when geographic isolation interrupts gene flow between two subpopulations. ... Intrinsic reproductive barriers may arise coincidentally as allopatric populations go down sepa- rate evolutionary paths due to mutation, genetic drift, and natural selection.
What is a sympatric population?
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation.
What is the greatest challenge to a successful sympatric speciation event?
Question: What Is The Greatest Challenge To A Successful Sympatric Speciation Event? Geographic Isolation Of The Groups Potential Homogenization Due To Gene Flow Between Groups Disruptive Selection On Phenotypic Traits Genetic Drift Due To Small Population Size.
What is the definition of sympatric speciation quizlet?
sympatric speciation. The formation of a new species as a result of a genetic change that produces a reproductive barrier between the changed population (mutants) and the parent population. No geographic barrier is present.
