True, because the purpose of mitosis is replacing cells for an individual so the whole species group would not be affected.

Detailed explanation-1: -Mutations provide the vital raw material for natural selection, so if the mutation rate is too low a population will not be able to evolve fast enough to keep up with environmental changes.
Detailed explanation-2: -The majority of mutations are neutral in their effects on the organisms in which they occur. Beneficial mutations may become more common through natural selection. Harmful mutations may cause genetic disorders or cancer.
Detailed explanation-3: -Mistakes during mitosis lead to the production of daughter cells with too many or too few chromosomes, a feature known as aneuploidy. Nearly all aneuploidies that arise due to mistakes in meiosis or during early embryonic development are lethal, with the notable exception of trisomy 21 in humans.
Detailed explanation-4: -Explanation: Meiosis is a type of cell division that produces gametes while mitosis is a type of cell division that produces somatic cells. If a somatic cell develops a mutation, it is most likely not harmful or does not change the organism in any way because only two cells are affected.
