Meiosis 1

Meiosis 1 Prophase 1

  • Chromosomes start to condense
  • New microtubules are forming a bipolar spindle
  • One of the two centrosomes moves to the opposite side of the nuclear envelope which begins to break up

Meiosis 1 Metaphase 1

  • One set of microtubules has tethered one chromosome of each type to one spindle pole and another set tethered its homologue to the other spindle pole
  • Chromosomes are aligned midway between the two spindle poles

Meiosis 1 Anaphase 1

  • One of each chromosome moves to a spindle pole
  • Its homologue moves to the opposite pole
  • Motor proteins and microtubules allow for this movement

Mesiois 1 Telophase 1

  • One of each type of chromosome has arrived at the splindle pole
  • The cytoplasm divides in most species
  • All of the chromosomes are still duplicated
