Where do the 2 cells that enter into Meiosis II come from?
A
Skin cells
B
Interphase
C
Sex organs
D
Meiosis I
Explanation: 

Detailed explanation-1: -The cells that enter meiosis II are the ones made in meiosis I. These cells are haploid-have just one chromosome from each homologue pair-but their chromosomes still consist of two sister chromatids . In meiosis II, the sister chromatids separate, making haploid cells with non-duplicated chromosomes.

Detailed explanation-2: -Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.

Detailed explanation-3: -In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.

Detailed explanation-4: -Meiosis I is followed by meiosis II, which resembles mitosis in that the sister chromatids separate and segregate to different daughter cells. Completion of meiosis II thus results in the production of four haploid daughter cells, each of which contains only one copy of each chromosome.

Detailed explanation-5: -At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.
