Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Meiosis I results in two cells. Meiosis II results in four cells.
A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Meiosis I results in formation of two daughter cells with half the number of chromosomes than the parent and in meiosis II the two daughter cells undergo normal mitotic division to form four haploid cells. Q.

Detailed explanation-2: -Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. Both produce two daughter cells from each parent cell.

Detailed explanation-3: -Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

Detailed explanation-4: -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-5: -Which of the following is true regarding meiosis I and meiosis II? Explanation: Meiosis I involves the separation of homologous chromosomes, while meiosis II involves the separation of sister chromatids.
