MITOSIS AND MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During meiosis, A new cell membrane forms at the center of the both cells producing four haploid (1n) cells in what phase?
A
telophase 2 and cytokinesis
B
metaphase 2
C
anaphase 2
D
telophase 1 and cytokinesis
Explanation: 

Detailed explanation-1: -The chromatids reach the poles, and uncoil into thin threadlike chromatin. The nuclear membrane reforms from 2 diploid (2n) cells into 4 haploid (n) Daughter cells.

Detailed explanation-2: -In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense. Cytokinesis splits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid.

Detailed explanation-3: -Meiosis is a type of cell division-like mitosis, but it results in four haploid cells with one-half the number of chromosomes as the original diploid cell. Meiosis occurs in plants only during sexual reproduction in specialized cells to produce a haploid egg cell.

Detailed explanation-4: -Telophase II: The cells pinch in the center and divide again. The final outcome is four cells, each with half of the genetic material found in the original. In the case of males, each cell becomes a sperm. In the case of females, one cell becomes an egg and the other three become polar bodies which are not used.
