Step 1
Speciation can occur in different ways, primarily through allopatric speciation (geographic separation) and sympatric speciation (occurring in the same geographic area). Show more…

2. The Isthmus of Panama cut off gene flow between Atlantic and Pacific populations of a species of fish. The cessation of gene flow led to the accumulation of genetic differences between the populations, which led to reproductive isolation. Now Atlantic and Pacific populations of this fish are separate species that cannot interbreed, even if they were again to come into contact with each other. The process described is that of a. sympatric speciation. b. parapatric speciation. c. allopatric speciation. d. reinforcement. e. temporal isolation.

Which of the following would best be described as a case of speciation in sympatry? Select one: a. Speciation cannot take place in sympatry – only in allopatry, where geography poses a barrier to gene flow. b. A population of lizards is subdivided by a natural barrier and subsequently diverges to form two species that cannot interbreed. c. A new, isolated population of fruit flies is founded by a small group of colonists, which then diverge from the ancestral source population. d. An individual hermaphroditic plant undergoes meiotic failure, producing diploid pollen and ovules; these self-fertilize, germinate, and grow into several fully fertile tetraploid plants.

The splitting of one species to form two or more species most commonly occurs a. by sympatric speciation. b. by genetic drift. c. by allopatric speciation. d. suddenly.
