Gene flow also know as gene migration is the transfer of genetic variations or characteristics from one population to another. The gene flow can be well illustrated using a flock of geese. A flock of geese migrate and enter into the territory of another flock of geese and start interbreeding. This will result to transfer of the different genes into the off springs.

You would be in G2 Phase. G2 phase is the third and final subphase of Interphase in the cell cycle directly preceding Mitosis. It follows the successful completion of S phase, during which the cell’s DNA is replicated. G2 phase ends with the onset of prophase, the first phase of mitosis in which the cell’s chromatin condenses into chromosomes.
