gametogenesis

• what is the production of gametes called

  gametogenesis
• What is gametogenesis?


  production of gametes
• what is meant by spermatogenesis

  this is the formation of sperm in the testes
• what is meant by oogenesis

  this is the formation of ova in the ovaries
• what is the name of the process by which ova is produced

  oogenesis
• what is the name of the process by which sperm is formed in the testes

  spermatogenesis
• what is the first stage of oogenesis

  a primary oocyte
• what is the first stage of spermatogenesis

  primary spermatocyte
• how many secondary oocytes are formed from the primary oocyte

  2
• how many secondary spermatocytes are formed from the primary spermatocyte

  2
• what is produced from the secondary spermatocyte

  4 spermatids
• what cells undergo mitosis and meiosis to form haploid gametes

  germinal epithelium cells
• what is produced from the secondary oocyte in oogenesis

  1 ovum and 1 polar bodie
• How many polar bodies are produced during oogenesis?

  3
• why is it important that gametes are haploid

  so that when fertilization occurs the diploid number is restored and the zygote has a full set of homologous chromosomes
• what is meant by diploid

  this is used to describe a cell that contains two copies of each chromosome
• what leads to genetic variation in the gametes

  crossing over in prophase 1 and independent assortment in metaphase 1 and metaphase 2
• what is meant by gonads

  sex organs
• Where does gametogenesis occur?

  gonads
