Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How does meiosis differ from mitosis?
A
It creates 4 genetically different gametes (haploid) while the other creates identical daughter cells (diploid)
B
One makes twins and the other doesn’t
C
It creates 8 genetically different gametes (diploid) while the other creates identical daughter cells (haploid)
D
One creates chromosome pairs and the other one only creates individual chromosomes
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: -Mitosis produces two genetically identical “daughter” cells from a single “parent” cell, whereas meiosis produces cells that are genetically unique from the parent and contain only half as much DNA.

Detailed explanation-3: -Mitosis involves the division of body cells, while meiosis involves the division of sex cells. The division of a cell occurs once in mitosis but twice in meiosis. Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis.

Detailed explanation-4: -The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell.

Detailed explanation-5: -During meiosis, the pairs of chromosomes separate and segregate randomly to produce gametes with one chromosome from each pair. Meiosis involves two nuclear and cell divisions without interphase in between, starting with one diploid cell and generating four haploid cells.
