Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many cells are produced during telophase I?
A
4
B
8
C
2
D
0
Explanation: 

Detailed explanation-1: -There are now four daughter cells-two from each of the two cells that entered meiosis II-and each daughter cell has half the normal number of chromosomes (Figure 7). Each also contains new mixtures of genes within its chromosomes, thanks to recombination during meiosis I.

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: -Telophase II: During telophase II, cell division begins again in each of the two daughter cells, creating 4 daughter cells. Each of these 4 daughter cells contains 23 chromosomes, making them haploid, and none of the 4 is exactly alike (due to crossing over and independent assortment).

Detailed explanation-4: -Telophase I results in the production of two nonidentical daughter cells, each of which has half the number of chromosomes of the original parent cell.

Detailed explanation-5: -During telophase I, the chromosomes are enclosed in nuclei. The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells.
