Once two populations of aspecies have become allopatric with some barrier preventinggene flow between them, the two populations are free to divergegenetically. One mechanism for divergence that is thought to resultin rapid divergence is sexual selection.
a. Why is sexual selectionlikely to result in more rapid changes in phenotype than typicalnatural selection in the same population?
Why is sexual selection likely to result in morerapid speciation than natural selection in the samepopulation?

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?
