meiosis

• what is meiosis?

  Meiosis is a special type of cell division that produces four daughter cells, each with half the number of chromosomes, and that this results in the formation of genetically different haploid gametes, which will develop into sex cells (sperm or eggs).
• where does meiosis occur?

  meiosis occurs in the reproductive organs.
• what are the reproductive organs in animals?

  the overies and testes
• How is meiosis different from mitosis?


  Meiosis involves two divisions, produces haploid cells, and creates genetic variation, while mitosis involves one division, produces diploid cells, and creates identical cells
• What type of cells does meiosis form?


  form gametes
• How many chromosomes does a zygote have?

  46
• Are gametes identical to the parents?

  gentically unidentical
• when a cell undergoes meiosis it produces _ gametes each with __ chromosomes

  4 gametes, each with 23 chromosomes
• gametes have haploid nucleus because they contain__________

  half the number of chromosomes (23).
• what does haploid mean?

  a cell that contains one set of chromosomes (23)

  (e.g. egg and sperm cell)
