Binary fission is a form of asexual reproduction. Therefore, when the organism splits, there is not genetic variation in its two offspring, which means that things such as mutations can be debilitating towards the organism.
In DBMS the data is stored in the form of table . Each row in DBMS is known as tuple.
The main disadvantage of binary fission is the passing of defects and disease directly to the offspring. Another disadvantage of binary fission is the chance of evolution being low, as no recombination of genes occurs in this process.
