Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Mutation is any hereditary change in the make up of an individual other than that which may be caused by the simple recombination of genes. Mutations may occur in any direction.

Evolution
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
