Final answer:
Meiosis and mitosis differ in the number of divisions, number of daughter cells produced, and genetic variation. However, they share similarities in DNA replication and the separation of sister chromatids.
Step-by-step explanation:
Meiosis and mitosis are both processes of cell division, but they differ in several ways. One of the differences is the number of divisions. Mitosis involves a single nuclear division, while meiosis consists of two nuclear divisions. Another difference is the number of daughter cells produced. Mitosis produces two genetically identical diploid daughter cells, while meiosis produces four genetically different haploid daughter cells.
Genetic variation is also introduced in meiosis but not in mitosis. During meiosis, homologous chromosomes pair, crossover, and exchange genetic material. This leads to the creation of genetically different daughter cells. In contrast, mitosis does not involve this mixing of genetic material.
However, meiosis and mitosis share similarities such as the replication of DNA and the separation of sister chromatids. The main differences occur during the first division of meiosis, where exchange of genetic material takes place.
