Question

Mention any one factor responsible for the process of speciation.

Answer 1

Speciation:

Speciation is the process through which new species arise from the existing species.

The factor that lead to speciation: Genetic drift

• Genetic drift is the alteration in the frequencies of the genes because of a chance event. Chance events are suddenly occurring events taking place in a small population. For example- flood, volcanic eruption, etc.
• The genetic drift leads to accumulation of alternation between two populations,

Other factors leading to speciation:

• Natural selection
• Geographical isolation
