CELL DIVISION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Process that includes two cell divisions.
A
Mitosis
B
Meiosis
C
Both Mitosis and Meiosis
D
None of the above
Explanation: 

Detailed explanation-1: -Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

Detailed explanation-2: -There are two divisions in meiosis; the first division is meiosis I: the number of cells is doubled but the number of chromosomes is not. This results in 1/2 as many chromosomes per cell. The second division is meiosis II: this division is like mitosis; the number of chromosomes does not get reduced.

Detailed explanation-3: -Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.

Detailed explanation-4: -Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase. A key difference, however, is that during meiosis, each of these phases occurs twice-once during the first round of division, called meiosis I, and again during the second round of division, called meiosis II.

Detailed explanation-5: -Mitosis involves one cell division, whereas meiosis involves two cell divisions.
