Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Mitosis and meiosis are both processes involved in reproduction. Which statement correctly compares mitosis and meiosis?
A
Mitosis and meiosis both produce genetic variation within their daughter cells
B
Mitosis results in the production of two genetically identical diploid cells and meiosis producesfour genetically unique haploid cells.
C
Mitosis and meiosis are both divided into only four distinct phases:prophase, metaphase, anaphase, and interphase.
D
Mitosis results in the production of two genetically unique diploid cells and meiosis produces fourgenetically identical haploid cells.
Explanation: 

Detailed explanation-1: -Comparison of the processes of mitosis and meiosis. Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

Detailed explanation-2: -D. Correct-Cells produced through mitosis contain DNA identical to the parent cells, whereas meiosis produces cells that are haploid and often genetically different. Bio.

Detailed explanation-3: -Mitosis and meiosis are both processes by which cells reproduce, but there are distinct differences between the two. While new cells are generated during mitosis, meiosis is a special type of cell division that produces sex cells for reproduction. The two processes were discovered by different scientists.

Detailed explanation-4: -o, the correct statement is ‘In both mitosis and meiosis the replication of DNA and chromosomes occurs at the same stage.

Detailed explanation-5: -Mitosis and meiosis are nuclear division processes that occur during cell division. Mitosis involves the division of body cells, while meiosis involves the division of sex cells. The division of a cell occurs once in mitosis but twice in meiosis.
