Polyploidy producing immediate reproductive isolation from the parent species exemplifies which mode of speciation?
- Acheck_circle
Sympatric speciation (in plants)
- B
Adaptive radiation
- C
Allopatric speciation
- D
Peripatric speciation
Explanation
Polyploidy can instantly create reproductive isolation within the same geographic area: tetraploids x diploids yield sterile triploids. It is a major mechanism of sympatric speciation, especially in plants.
