What are the most common mechanisms of sympatric speciation and in which major group of organisms does this happen most often? Distinguish between sympatric and allopatric and parapatric speciation. Which is considered the (far) more common mechanism of species formation? What does "gene flow" between populations do?

1. Allopatric speciation is most likely to occur in which of the following scenarios? Group of answer choices There are two distinct possible feeding strategies within a given population, causing the rise of two species living in the same geographic area. All of the “parent” species of a new species go extinct, reducing gene flow between populations. A mutation changes the mating ritual followed by a subset of individuals in a population, and they end up forming an all-new species....
