WebMutation in Mitosis and Meiosis. Mutations can be: positive – have a good effect on the organism. negative – be detrimental or fatal. neutral – have no effect (repetition of triplet … WebAccording to this (old) paper there are 10 times more mutations during meiosis than during mitosis. One reason for that is that recombination often causes replication error and therefore mutations. However, in many multicellular organisms, germ cells undergo many cell divisions (mitosis during development) before finally undergoing meiosis.
WebMar 31, 2024 · Mutations may also occur during the processes of mitosis and meiosis when sister chromatids and/or homologous chromosomes are separated from one another. In nature, mutagenesis, or the process of generating DNA mutations, can lead to changes that are harmful, beneficial, or have no effect.
