Question

Understand that the different mechanisms of isolation – geographic (including environmental disasters, habitat fragmentation), reproductive, spatial, and temporal – influence gene flow?

Answer 1

Different mechanisms of isolation, including geographic, reproductive, spatial, and temporal, influence gene flow between populations.

Step-by-step explanation:

Isolation of populations occurs through different mechanisms, such as geographic, reproductive, spatial, and temporal isolation, which can all influence gene flow. Geographic isolation refers to physical barriers like rivers or mountains that separate populations. Reproductive isolation occurs when populations can no longer interbreed due to differences in mating behaviors, anatomy, or reproductive timing. Spatial and temporal isolation involve populations being in different locations or reproducing at different times, preventing gene flow between them.
