Which of the following statements best explains the process of allopatric speciation?
| Genetic differences accumulate between populations that are isolated by a geographic barrier, eventually leading to reproductive isolation. |
| Genetic differences accumulate through recombination between populations that are interbreeding, eventually leading to reproductive isolation. |
| Genetic differences accumulate in a population through selective mate choice, leading to two groups that breed independently, causing reproductive isolation. |
| Two populations in the same geographical area accumulate genetic differences by random chance, eventually leading to reproductive isolation. |
| Genetic changes within a population as the result of genetic drift influences traits involved with mate choice, eventually leading to reproductive isolation. What is the basic difference between allopatric and sympatric modes of speciation?
