Answer: Mutation. The allelic variations that make evolution possible are generated by the process of mutation, but new mutations change gene frequencies very slowly, because mutation rates are low. Assume that the gene allele A1 mutates to allele A2 at a rate m per generation and that at a given time the frequency of A1 is p.

Answer: S- phase of cell cycle
Explanation:
Cell cycle is a cyclical process taken place in a cell leading to duplication of its DNA and division of cytoplasm to form two daughter cells.
The S phase of a cell cycle is an important part of the cycle which is found during interphase stage before either mitosis or meiosis.
The S phase of cell cycle is responsible for the replication of DNA. This replication DNA causes it to double before it enters mitosis or meiosis.
