<span>When a gene changes within a population over time, it is referred to as evolution. This refers to a long but steady rate of mutations that occur in genes of organisms within the environment. A lot of factors affect a population's evolution (e.g. climate, reproduction, food source) and it is a determinant whether a species will survive for the next generations. </span>
Mitosis is used to produce daughter cells that’s genetically identical to parent cells. And Mitosis affects change by the cell copying or “replicating” its chromosomes, and then splitting the copied chromosomes equally to make sure that each daughter cell has a full set.
