meiosis

• What is meiosis?

  a form of cell division that produces four non-identical, haploid sex cells or gametes
• What is a diploid?

  A diploid is an organism or cell that has two sets of chromosomes.
• What is a haploid?

  A haploid is a cell or organism that has only one set of chromosomes.
• What happens in Meiosis 1?

  Homologous chromosomes separate.
• What are homologous chromosomes?

  chromosomes that consist of one maternal and one paternal chromosome as a pair
• What are the stages of Meiosis 1?

  Prophase 1, Metaphase 1, Anaphase 1, Telophase
• What happens in prophase 1?

  homologous chromosomes align along their length by a process called synapsis
• What is synapsis?

  the fusion of chromosome pairs at the start of meiosis.
• What happens in metaphase 1?

  Homologous chromosomes line up at the equator of the cell.
• What happens in anaphase 1?

  Homologous chromosomes separate and move to opposite poles of the cell.
• What happens in telophase 1?

  The chromosomes gather at the poles of the cell
• What are spindle fibers?

  Microtubules that form during cell division and help separate chromosomes.
