| Reproductive isolation between segments of a single population is termed as |
| a) | Sympatry | b) | Allopatry |
| c) | Population divergence | d) | Disruptive divergence |
| (a)Sympatry is the condition when selection may produce ecotypes living in adjacent habitats in the same geographic area and gives rise to sympatric speciation, i.e., formation of species within a single population by reproductive isolation or without geographical isolation. |
