Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
At the end of mitosis, there are:
A
2 cells, genetically identical
B
2 cells, genetically different
C
4 cells, genetically identical
D
4 cells, genetically different
Explanation: 

Detailed explanation-1: -Mitosis is a fundamental process for life. 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-2: -Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell.

Detailed explanation-3: -Mitosis produces two daughter cells that are genetically identical to each other, and to the parental cell.

Detailed explanation-4: -Meiosis I ends when the chromosomes of each homologous pair arrive at opposing poles of the cell. The microtubules disintegrate, and a new nuclear membrane forms around each haploid set of chromosomes. The chromosomes uncoil, forming chromatin again, and cytokinesis occurs, forming two non-identical daughter cells.

Detailed explanation-5: -The daughter cells from mitosis are called diploid cells. Diploid cells have two complete sets of chromosomes.
