Gametogenesis is the process whereby normal somatic cells, which contain a diploid number of chromosomes (46 = 44 autosomes and 2 sex chromosomes), are converted to specialized reproductive cells that have half the number of chromosomes or are haploid (23 = 22 autosomes and 1 sex chromosome).
  • These specialized reproductive cells are called gametes.
  • The process by which this is possible is called meiosis and involves cell division without the replication of chromosomes.
  • The specific process of gamete production in females is called oogenesis and in males it is called spermatogenesis.
