Both sympatric and allopatric speciation involve the formation of new species through the genetic isolation of populations. In both cases, reproductive barriers develop that prevent gene flow between populations, leading to divergence and eventually the formation of separate species. The key difference between the two is that sympatric speciation occurs within the same geographic area, while allopatric speciation involves speciation due to geographic isolation.
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.
This type of evolution is known as allopatric speciation, where populations of a species become isolated geographically and evolve independently due to different environmental pressures. Over time, these populations may become distinct species with unique traits and adaptations.
When plants undergo allopatric speciation, an initial reproductive barrier is often geographic isolation, which prevents different populations from interbreeding. This isolation can occur due to physical barriers such as mountains, rivers, or distance. Over time, genetic divergence can lead to the development of distinct species as populations adapt to their unique environments and evolve different traits. Eventually, these differences may become significant enough to prevent interbreeding even if the populations come back into contact.
Another name for geographic isolation is allopatric isolation. This refers to a type of isolation where populations become reproductively isolated due to physical barriers preventing gene flow between them.

Yes, allopatric speciation is more likely to occur on an island close to a mainland because geographic isolation plays a key role in driving speciation. Isolation on an island can lead to reproductive barriers and genetic divergence, promoting the process of allopatric speciation. With limited gene flow from the mainland, unique evolutionary trajectories can lead to the formation of new species on the island.
reproductive, behavioral, geographic, and temporal
This is an example of geographic isolation, a type of allopatric speciation where physical barriers prevent gene flow between populations, leading to the accumulation of genetic differences and eventually reproductive isolation.
Geographic isolation as a mechanism for reproductive isolation. In sympatric speciation, new species arise within the same geographic area without physical barriers separating populations. This process typically involves ecological, behavioral, or genetic factors leading to reproductive isolation within a single population.
That would be geographic isolation and reproductive isolation. Both could lead to speciation.

Reproductive isolation is a type of speciation. Reproductive isolation is when a species divides forming two subspecies, due to different mating periods.
