Most mutations relevant to evolution occur because A. of DNA replication during mitosis B. of DNA replication errors during meiosis C. of mutagens such as UV light D. All of the above E. A & B only   Group of answer choices A. B. C. D. E.

A mutation is a change in a cell's DNA's nucleotide sequence. Mutations can take many different forms. Before, during, and after mitosis and meiosis, mutations can take place. A mutation can be passed on to offspring and increase the genetic diversity of the population if it happens in the cells that will undergo meiosis to produce gametes or during the process itself. The only possible source of genetic diversity in asexual reproduction is mutations. In most cases, mutations are detrimental or neutral to progeny, but they can occasionally be advantageous.
