An experiment was conducted by Diane Dodd in which a single population of fruit flies was divided into two, with one of the popu
lations fed with starch-based food and the other with maltose-based food. After the populations has diverged over many generations, the groups were again mixed; it was observed that the flies continued to prefer mating with others from the same original population. This process could eventually result in:___________.
Allopatric speciation occurs when new distinct species are formed due to the separation of a specie into two separate groups. These two groups are kept away from each other.
In allopatric speciation there is no exchange of genes between the two separate groups.
Allopatric speciation can also be known as geographical speciation.
