Mitosis has one DNA replication, while meiosis has two DNA replications

|
In mitosis, on e nuclear division occurs. In meiosis, two nuclear divisions occur.

|
|
In mitosis, homologous chromosomes pair up. In meiosis, there is no pairing of chromosomes.

|
Mitosis results in the production of gametes, while meiosis results in the production of body cells.

Detailed explanation-1: -Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
Detailed explanation-2: -Mitosis is a type of cell division for somatic cells and for the asexual reproduction of unicellular eukaryotic cells. Meiosis is the type of cell division for the production of gametes in sexual reproduction.
Detailed explanation-3: -Nuclear divisions occur in both mitosis and meiosis. In mitosis, the result is the division of duplicated copies of genome into two. In meiosis, nuclear division occurs twice, dividing the originally single nucleus into four nuclei that are genetically different from one another.
Detailed explanation-4: -Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division.
Detailed explanation-5: -Mitosis is a single nuclear division that results in two nuclei, usually partitioned into two new cells. The nuclei resulting from a mitotic division are genetically identical to the original. They have the same number of sets of chromosomes: one in the case of haploid cells, and two in the case of diploid cells.
