Explanation:
Detailed explanation-1: -Meiosis does not replace the lost cells and has no role in cell repair.
Detailed explanation-2: -Meiosis is responsible for the formation of sex cells or gametes that are responsible for sexual reproduction. It activates the genetic information for the development of sex cells and deactivates the sporophytic information. It maintains the constant number of chromosomes by halving the same.
Detailed explanation-3: -Solution : Significance of meiosis lies in production of genetic variability, maintaining constancy of chromosomes number during sexual reproduction and reduction of chromosomes number to one half.
Detailed explanation-4: -Complete answer: The stage of DNA replication occurs, but not in meiosis.
