Detailed explanation-1: -This is false mutations can happen during any stage of cell division.

Detailed explanation-2: -Importantly, new mutations also occur during meiosis, at frequencies much higher than during the mitotic cell cycles. These meiotic mutations are associated with genetic recombination and depend on double-strand breaks (DSBs) that initiate crossing over.

Detailed explanation-3: -A spontaneous mutation may be due to a mistake during DNA replication. Mutations may also occur during mitosis and meiosis.

Detailed explanation-4: -As opposed to germ-line mutations, somatic mutations occur in cells found elsewhere in an organism’s body. Such mutations are passed to daughter cells during the process of mitosis (Figure 2), but they are not passed to offspring conceived via sexual reproduction.

Detailed explanation-5: -The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
