Question

Differentiate between Geographical and reproductive isolation.

Answer 1

Aspect	Geographical Isolation	Reproductive Isolation
Definition	A reproductive barrier due to physical/geographical boundaries that prevent individuals from different populations from meeting or mating.	Prevention of interbreeding between populations of two different species due to reproductive barriers.
Nature of Barrier	Physical or geographical (e.g., mountains, rivers, distance).	Biological or behavioral mechanisms that prevent mating or fertilization.
Effect on Populations	Populations become physically separated and unable to interbreed naturally.	Populations may live in the same or overlapping areas but cannot interbreed successfully.
Outcome	Leads to genetic divergence due to isolation, potentially resulting in speciation.	Maintains species boundaries by preventing gene flow between species.
