It is temporary and reversible. There are two distinct types of electromeric effects: (i) Positive Electromeric Effect (+E effect): In this effect the \(\pi \)-electrons of the multiple bond are transferred to that …
WebMutation is a source of new alleles in a population. Mutation is a change in the DNA sequence of the gene. A mutation can change one allele into another, but the net effect is a change in frequency. The change in frequency resulting from mutation is small, so its effect on evolution is small unless it interacts with one of the other factors ...
