Answers & explanation:
I - False
A sympatric speciation can occur commonly in both animals and plants. Sympatric speciation events are very common in plants because it is normal for them to develop multiple sets of chromosomes.
II - False
Sympatric speciation occurs without geographic variation. When two populations of the same species live in the same area but there is no crossing between populations, sympatric speciation occurs.
III - True
Sympatric species may indeed lead to the formation of new species. Sympatric speciation is believed to be responsible, for example, for the large number of cichlid fish species found in Lake Victoria on the African continent. According to research, this lake was colonized by only one ancestral species.
