Anaphase I

ANAPHASE I

Anaphase 1

  • Chromosomes move to the opposite cell poles.
  • Similar to mitosis, the microtubules and the kinetochore fibers interact to cause the movement.
  • A key difference between mitosis and meiosis is that sister chromatids remain joined after metaphase in meiosis I, whereas in mitosis they separate.
  • During this stage, the original maternal and paternal chromosomes separate, thereby reducing the number of chromosomes from 2N to N number, yet the sister chromatids remain together.
