Briefly describe the process of speciation, and define allopatric speciation
What will be an ideal response?
When mutations occur in one population or subpopulation that are not passed to another population or subpopulation, or if natural selection favors different genes in different populations, speciation can occur if gene flow becomes restricted permanently between the two populations (i.e., they can no longer mate and produce fertile offspring). If a physical boundary such as a stream divides the two populations, restricting gene flow between them, and a speciation event occurs, this is termed allopatric speciation.
