Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which phase of meiosis? Nuclear membrane forms around each group of chromosomes, the cytoplasm divides forming 2 daughter cells, sister chromatids remain together
A
telophase 2
B
telophase 1
C
metaphase 1
D
prophase 2
Explanation: 

Detailed explanation-1: -In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.

Detailed explanation-2: -During telophase I, a nuclear membrane forms around each cluster of chromosomes.

Detailed explanation-3: -Finally, during telophase, a nuclear membrane forms around each set of chromosomes to separate the nuclear DNA from the cytoplasm.

Detailed explanation-4: -Cytokinesis starts during the nuclear division phase called anaphase and continues through telophase.

Detailed explanation-5: -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.
