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.
WebMeiosis is necessary for the synthesis and proliferation of gametes. Gametes are the cells that take part in sexual reproduction. The sperm and ova in the case of humans are produced as a result of meiosis. Chromosome Number Maintenance.
