Question

34. i) Define Speciation ? Explain how speciation occurs
ii) Will Geographical isolation be a major factor in the speciation of a
self pollinating plant species ? Give reason for your answer​

Answer 1

Speciation occurs when two or more populations become so genetically distinct that they no longer interbreed with one another. There are multiple ways this canoccur. The natural waysspeciation can occur are allopatric, parapatric, and sympatric speciation.

Scientists think that geographic isolation is a common way for the process of speciation to begin: rivers change course, mountains rise, continents drift, organisms migrate, and what was once a continuous population is divided into two or more smaller populations
