Question
Allopatric and Sympatric speciation.
| Allopatric speciation | Sympatric speciation |
| 1. Allopatric speciation is the formation of a new species due to separation of a segment of population from the original population. | 1. Sympatric speciation is the formation of species within single population. |
| 2. There is geographical barrier cutting across the species range during such speciation. | 2. There is no geographical isolation during sympatric speciation. |
| 3. Allopatric speciation does not have physiological barrier. | 3. Sympatric speciation is due to physiological or reproductive isolating barrier. |
| 4. Migration of individual are also helpful in allopatric speciation. E.g. African elephant and Indian elephant. | 4. Mutations are helpful in sympatric speciation. E.g. Cichlid fishes in Lake Victoria. |
