WebAug 20, 2014 · How can a mutation lead to evolution? If a mutation results in a trait that will increase the likelihood that the individual having the mutation will survive, mate, and produce offspring that have the same mutation, then that population will evolve. WebIn sexual reproduction, chromosomes can sometimes swap sections during the process of meiosis (cell division), thereby creating new genetic combinations and thus more genetic variation. Although DNA replication is tightly regulated and remarkably accurate, errors do occur and result in mutations, which are also a source of genetic variation. WebNot only does fertilization lead to the mixing of paternal and maternal chromosomes, but it also induces a number of changes in the egg cytoplasm that are critical for further development. These alterations activate the egg, leading to the completion of oocyte meiosis and initiation of the mitotic cell cycles of the early embryo. fis core system
