Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Daughter cells produced in meiosis have
A
one-fourth the number of chromosomes as daughter cells produced in mitosis.
B
half the number of chromosomes as daughter cells produced in mitosis.
C
the same number of chromosomes as daughter cells produced in mitosis.
D
twice the number of chromosomes as daughter cells produced in mitosis.
E
four times the number of chromosomes as daughter cells produced in mitosis.
Explanation: 

Detailed explanation-1: -Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

Detailed explanation-2: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II. At the end of meiosis I there are two haploid cells.

Detailed explanation-3: -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.

Detailed explanation-4: -Mitosis is a type of cell division that produces two identical daughter cells from a single diploid cell. Mitosis occurs in nearly every cell in the human body.

Detailed explanation-5: -The number of chromosomes in human cells are 46. i.e, these are present in pairs of 23. These pairs break apart and get separated in meiosis I. Thus, each of the two daughter cells formed after first meiotic division have half the number of chromosomes, i.e., 23.
