Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A somatic cell with 20 chromosome undergoes MIEOSIS, how many chromosomes will each daughter have?
A
20
B
10
C
40
Explanation: 

Detailed explanation-1: -Meiosis is also called reduction division. This type of cell division is involved in formation of gametes. The number of chromosomes is reduced to half at the end of meiosis. So, a cell having 20 chromosomes will give rise to four daughter cells having 10 chromosomes after meiosis.

Detailed explanation-2: -Complete answer: If an organism has 20 chromosomes, then the number of chromosomes the daughter cells have after mitosis is 20 because when a cell divides by the process of mitosis it produces two clone daughter cells having the same number of chromosomes (20) as the parent cell has.

Detailed explanation-3: -A cell with 10 chromosomes undergoes mitosis. The number of chromosomes that each of the new cells will have is c. 10 chromosomes each. Mitotic division results in two daughter cells with an identical chromosomal number and genetic content to the parental cell.

Detailed explanation-4: -At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

Detailed explanation-5: -Answer and Explanation: If a cell containing 10 chromosomes divides by mitosis two daughter cells will be produced. Mitosis is the process of cell division and creates two identical daughter cells from one parent cell.
