Which of the following is not the significance of meiosis?Formation of gametesMaintenance of chromosome number in zygoteIntroduction of variationsRepairing and healing of wounds

The option that is not the significance of meiosis is "Repairing and healing of wounds".

Meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell. It is involved in the formation of gametes (sex cells), maintaining the chromosome number in a zygote (fertilized egg), and introducing variations through genetic recombination.

However, meiosis is not involved in the repairing and healing of wounds. This process is typically associated with mitosis, another type of cell division, where cells divide and replicate to replace damaged or dead cells.
