MCQ
Meiosis:
  • A process where a single cell divides twice to produce four cells containing half the original amount of genetic information.
  • B
    A process where a nucleus divides twice to produce four cells containing the original amount of genetic information.
  • C
    A process where a cell divides thrice to produce four cells containing half the original amount of genetic information.
  • D
    A process where a DNA divides twice to produce eight cells containing half the original amount of genetic information.

Answer

Correct option: A.
A process where a single cell divides twice to produce four cells containing half the original amount of genetic information.
(a) A process where a single cell divides twice to produce four cells containing half the original amount of genetic information.
Explanation:
In meiosis, a single cell undergoes two successive nuclear divisions (meiosis I and meiosis II) resulting in four daughter cells, each with half the number of chromosomes of the original cell, thus introducing genetic diversity. This process is essential for sexual reproduction and occurs in the germ cells to produce gametes (sperm and eggs).
