Key Concepts Covered

➡️ Speciation – The evolutionary process where populations develop into distinct species over time
➡️ Reproductive Isolation – Mechanisms preventing gene flow between populations, leading to speciation
➡️ Allopatric Speciation – Speciation that occurs when populations are geographically separated
➡️ Sympatric Speciation – The emergence of new species within the same geographic area
➡️ Mechanisms of Reproductive Isolation – Behavioral, temporal, mechanical, and genetic barriers that maintain species boundaries

Question Types / Formats
