In bacteria, binary fission can be modeled in three stages. These stages typically include the replication of the bacterial DNA, the segregation of the DNA into two daughter cells, and finally the division of the cytoplasm to form two separate cells.

Without external forces, the third generation of a bacterium and the original parent cell will have approximately 100% matching DNA sequences. This is because bacteria replicate their DNA through binary fission, resulting in daughter cells that are genetically identical to the parent cell.
