Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In what form are the daughter cells and chromosomes just after meiosis II has finished?
A
haploid, tetrads (homologs w/ sister chromatids) are joined
B
diploid, sister chromatids have separated
C
haploid, sister chromatids have separated
D
diploid, tetrads (homologs w/ sister chromatids) are joined
Explanation: 

Detailed explanation-1: -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. In humans, the products of meiosis are sperm or egg cells.

Detailed explanation-2: -The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.

Detailed explanation-3: -Originally, there were two cells that underwent meiosis II; therefore, the result of meiosis II is four cells, each with 23 chromosomes. Each of the four cells is haploid; that is, each cell contains a single set of chromosomes.

Detailed explanation-4: -However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell. 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-5: -Meiosis II closely resembles mitosis. The two daughter cells move into this phase without any further chromosome duplication. The sister chromatids are pulled apart during this division. A total of four haploid daughter cells are produced during the course of meiosis II.
