One is unequal crossing over, in which recombination happens between different positions on chromosomes that are misaligned during meiosis. 

Another is replication slippage, in which the DNA polymerase loses its place and copies a segment of chromosome twice.

The lac operon has three paradoxes

1-If the operon is in a repressed state, how does the inducer enter the cell to start the process of induction

2- If the operon is in a repressed state, how Repressor is removed with allolactose 

3- How is allolactose synthesized in Repressed state Answer is Leaky Expression
