Question

Quizplus · Accepted Answer

Sympatric speciation is the only type of speciation that can occur within a single generation without any physical barriers separating populations. This can occur through mechanisms such as polyploidy, disruptive selection, or chromosomal rearrangements, resulting in the formation of new species. Allopatric speciation involves geographic separation of populations, leading to divergence over time, while parapatric speciation occurs when neighboring populations are in contact but have a partial barrier preventing gene flow. Artificial speciation refers to intentional human intervention to create new species, and microevolution refers to small-scale changes within a population.
