MITOSIS AND MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
After meiosis, are the cells identical?
A
Yes
B
No
Explanation: 

Detailed explanation-1: -The resulting cells from meiosis are not genetically identical because of the recombination of genes that occurred during prophase 1. Sex cells in humans are produced by meiosis. In males, all four child cells are sperms while in females, one child cell is an egg and the other 3 are polar bodies.

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: -During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes.

Detailed explanation-4: -Unlike the sister chromatids in mitosis, the sister chromatids in meiosis are not genetically identical due to crossing over. Telophase II: During telophase II, cell division begins again in each of the two daughter cells, creating 4 daughter cells.
