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.
Some obstacles to sympatric speciation include gene flow between populations, which can prevent divergence, as well as competition for resources within the same habitat. Additionally, lack of strong selection pressures or mechanisms driving reproductive isolation can impede the formation of new species within a single geographic area.
This process is known as sympatric speciation, where a new species evolves from a common ancestor within the same geographical area without a physical barrier. It can happen due to factors like polyploidy, habitat differentiation, or behavior isolation.
Plants, such as flowering plants like sunflowers and cotton, have often undergone sympatric speciation through polyploidy. This process involves the duplication of chromosomes within a single species, leading to the formation of new species that can coexist in the same geographic area. Polyploidy can facilitate rapid diversification and adaptation to new environments, contributing to the evolutionary success of certain plant lineages.
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.

Allopatric and sympatric speciation are both methods by which new species arise. However, allopatric speciation is when species interbreed. Sympatric speciation is when several new species arise from a common ancestor.

Sympatric Speciation
behavioral isolation
sympatric speciaton
sympatric speciation. This occurs when two subpopulations of a species evolve into distinct species without geographical isolation, often due to factors such as disruptive selection or polyploidy.
They both are mechanisms by which new species arise
Sympatric speciation refers to the formation of two or more descendant species from a single ancestral species all occupying the same geographic location. Often cited examples of sympatric speciation are found in insects that become dependent on different host plants in the same area.
When there is no physical barrier, a new species arises within the home range on an existing species.
Sympatric Speciation
characteristics of organisms that have been altered by the selective pressure of competition; the tendency for enhanced character divergence in the sympatric populations of two species that are partly sympatric and partly allopatric in their distributions, owing to the selective forces of competition.
