Genetic effects
Binary fission is asexual; offspring are supposed to be genetically identical to the parent cell, but due to mutation, daughter cells may have slightly differed genetic makeups.
Bacterial DNA has a relatively high mutation rate. This rapid rate of genetic change is what makes bacteria capable of developing resistance to antibiotics and helps them exploit invasion into a wide range of environments.
Organisms that reproduce through binary fission generally have exponential growth phases. Escherichia coli cells are able to divide every 20 minutes under optimum conditions during their exponential growth phase.
