Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A human cell has 46 chromosomes before mitotic division. How many chromosomes will the daughter cells after mitosis.
A
12
B
23
C
46
D
92
Explanation: 

Detailed explanation-1: -After cytokinesis and karyokinesis, the cell divides into two each daughter cell having the 46 chromosomes forming a total of 92 chromosomes in two cells divided.-Option B)

Detailed explanation-2: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids.

Detailed explanation-3: -Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.

Detailed explanation-4: -At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2.

Detailed explanation-5: -Both the daughter cells after the telophase stage will have the same number of chromosomes. When there are 46 chromosomes at the initial stage of mitosis, then daughter cells will have 46 chromosomes.
