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: -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: -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: -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.
